Music sampling takes many forms, but for the purposes of this paper
assume that the samples are of modest length (1-5 seconds).
Sometimes an entire performance is "sampled", as part of a "remix", but
that is a separate case entirely.
Assume the sampling is taken from published recordings; ie the samples are not recreated in the studio.
The music industry line here is that any use of copyrighted material requires permission; this gives the rights-holder the opportunity to set a fee limited only by the law of supply and demand. Fair Use is the one exception to this, but is not recognized by the industry and there are few music-related legal cases. While clearly there is no effect whatsoever of modest-length sampling on the market for the original, there might be (and in fact is) a "secondary" market for sampling rights that is affected. The copyright law itself only refers (§107(4)) to "the effect of the use upon the potential market for or value of the copyrighted work". Some have tried to argue that this also includes the market value of any portion of the entire copyrighted work, though this is a stretch.
For a discussion as to why Fair Use sometimes seems to be avoided in music lawsuits, see Edward Lee's Fair Use Avoidance in Music Cases.
If you prefer to take an ethical approach, here are a few ideas you might wish to consider. When sampling, what exactly is your obligation to the original artist? Must the sample be some form of homage? If so, why? Is it simply a matter of acknowledging credit for the sample? Can the credit be implicit, or must the original artist's name be spelled out? What if the sampling is not about "homage" at all (as in the Schnauss v Guns 'n Roses case)? Are artists really entitled to royalties when their work is sampled? Is making money from someone else's work without compensation ever permissible? Does it matter if the use in question is of someone's voice, versus an instrumental segment? After all, the instrumental segment can in principle be reproduced by other musicians, but imitating someone else's voice can be impossible.
Here is one way to view the conflict:
If you do not accept the first point here entirely, explain why! What conditions might be necessary for Fair Use to apply? Must there be some sort of "transformative" use? Is sampling fundamentally a "productive" use, ie use that is associated with some benefit to society? Or is it a "consumptive", or even parasitic, use? Does it matter if the sample is recognizable? Not recognizable? When considering the effect on the market, should the secondary market for sampling rights count, or just the market for the original work? As for the second point, what are appropriate limits for profiting from someone else's work?
An alternative argument is that, at least for singing, a person has a right to control the use of their own voice. You can also apply that to instrumental music, though maybe the argument is less compelling.
Chuck D, of Public Enemy, has claimed that "sampling [in hip-hop] basically comes from the fact that rap music is not music. It's rap over music" (http://www.stayfreemagazine.org/archives/20/public_enemy.html) Does this matter?
We have a grand Utilitarian bargain justifying copyright: we abide by copyright to create an incentive for authors. Does this bargain extend to publishers, even if authors won't be affected to a significant extent?
Sci-hub is a huge repository of scientific papers available for free over the Internet, founded by Alexandra Elbakyan. As of today you can still access it at sci-hub.se, but litigation from journal publishers has shut down sci-hub.org, sci-hub.ac, and several others. If all else fails, try using the tor browser and accessing scihub22266oqcxt.onion. To access a journal, first find its doi, or document object identifier (eg doi.org/10.1016/0168-0072(89)90038-9), by looking the paper up in google. Then paste the doi into the Sci-hub search box. (Sometimes Sci-hub presents you with a "captcha" box, with instructions in Russian.)
Traditionally, if you submit a scientific paper to a journal, and they agree to publish it, then they ask you to assign the copyright to them. At this point it is unlawful to distribute copies of the paper, although some journals are flexible about this. You do not get any royalties; in fact, you are likely to be charged a publication fee. In technical fields, authors are expected to do their own electronic typesetting. And peer reviewers are not paid either. Many sites no longer receive paper copies of journals; everything is electronic.
The journal publishers then sell subscriptions to libraries. These subscriptions are remarkably expensive. Academic libraries typically spend multiple millions of dollars (some detailed information is here).
It is generally believed that, when Aaron Swartz downloaded four million papers from JSTOR, his ultimate goal was to make them publicly available. Sci-hub has done exactly that, but now has almost 65 million papers. And, through a shadowy network of activists who have online access to extensive libraries, if Sci-hub doesn't have the paper you want then they can usually get it quickly.
Sci-hub has made journal publishers apoplectic. Some publishers are non-profit (like the American Chemical Society) and some are for-profit, such as Springer and Elsevier. But Sci-hub is based in Kazakhstan, pretty much out of reach of copyright law (the servers may have migrated elsewhere).
On the face of it, Sci-hub is a flagrant violator of copyright law. But there are two caveats:
The second argument is not really a Fair Use argument, but it completely undermines the Utilitarian justification for copyright. How much should we put up with onerous restrictions put in place by publishers, just for the sake of their own profits? For music and movies, if the creators aren't paid then the supply will dry up, but not here. Does this matter?
There are now open-access journals that make all content freely available. But by and large these are not the "top" journals, the for-profit ones that most advance a scientist's reputation, mainly because top journals are highly selective about what papers they accept and open-access journals have a harder time of that. Open-access journals also charge authors (or their grants, or their institutions) a lot more than traditional journals. For-profit journals lean heavily on this argument that their selectivity is contributing value to the scientific publishing process. But journal reputation is a rather indirect benefit to authors; is it sufficient to create an obligation? On the one hand, because publishers don't contribute directly to the financial incentive for authors, maybe they shouldn't get the benefit of copyright. On the other hand, authors do sign over their copyright rights to the publishers, and so maybe that is enough.
The social cost of journal paywalls is considerable. Many researches from poorer institutions simply cannot afford broad access. This includes many US institutions; the situation at third-world institutions is even worse. Scientists in Sierra Leone missed some important data about the Ebola virus during the 2014-16 outbreak because they could not afford the journals. That said, we don't really know the social costs of abandoning closed publishing. Some have argued that such a move would undermine the standards of excellence in scientific work, as getting published in an open journal is often easier. But, then, maybe highly selective open-access journals will increase in number.
There is no legal justification (involving Fair Use or otherwise) of Sci-Hub, unlike for music sampling. However, there is an ethical social-benefit argument to be made. One argument is that scientific information should be free, period; another is that the results of publicly funded research should be free (though authors and artists creating works with government funding (eg from the NEH) are allowed to sell their works). There is also the failure of the utilitarian argument against infringement: Sci-hub will not cause any scientist to write fewer papers. Musicians might get some money from sampling fees, but scientists receive absolutely no direct financial benefits from journal sales. Should we stick with the utilitarian copyright argument anyway? Or is there a deontological argument that applies here?
Make a case and come to a decision. Is the use of Sci-hub wrong? Should all journals migrate to an open-access policy? Do scientific publishers add real value? Should copyright law be strictly enforced here? Why or why not?
Your paper will be graded primarily on the following:
