I know there are tons of sites out there that list song lyrics that are surrounded with advertisements and pop up ads. I don't imagine the song writers had this in mind when they were writing their songs.
In any case, if someone wanted to analyze the lyrics of a song in a scholastic way, and quoted the source, and perhaps even sent users to where they could purchase the song and give that artist money...
Is this a copyright violation?
Is it different than citing a source in an academic paper?
Most of those lyric sites are not actually licensing the content, and are breaking the law. If they don't pay royalties, they may be liable for copyright violation.
There is a concept in copyright law called Fair Use. You should study the rules closely if you plan to use any copyright material, as the rules are subtle and not always obvious. The basic idea is that if you quote a small fraction of a work (for example, one or two lines of a song) for certain purposes (for example, as a part of a scholarly research paper), it may be OK to do so without seeking the copyright holders permission. Because reprinting all of a song's lyrics is not a small fraction of the work, it does not fall under fair use.
You are, in effect, asking whether such use constitutes fair use under copyright law.
That determination is highly fact-specific, so any answer here must have an "it depends" component. The factors that are considered include:
