To understand how the 1995 Act and the DMCA change music licensing, one should be aware that, in general, two distinct copyrights exist for each song that is recorded: the song copyright and the sound recording copyright.

Therefore, every time someone covers one of Bob Dylan's songs, Dylan, through his music publisher, receives a royalty payment because the song copyright protects him. The artist and producer who cover the Dylan song are only creating a sound recording of a song, and therefore only have a copyright on their particular version of the song, and not on the underlying song itself.
