This is a very contentious issue and depends on the country the music is stored in, the country it is being downloaded in, the relationship the site has with the copyright owners and whether or not a copyright even exists on the music.

Napster's original incarnation was shut down for making music downloadable for free without permission from the copyright owners. One way around copyright laws is by downloading music that has been released into the public domain under licenses such as the Creative Commons attribution-non commercial share-alike license which allows the music to be freely copied and manipulated so long as the original author is credited and that it is distributed under the same license.
