As people here like DRM-free stuff, I figured we should make a list of websites where you can download DRM-free music.
edit: as Kabuto rightfully pointed out, there is more need for list of websites featuring FLAC, as most have drm-free nowadays.
bandcamp.com lots of indie artists, good bandwidth, downloads in any format (FLAC, Ogg, MP3, etc.)
magnatunes.com hand-picked, high quality, full preview (FLAG, Ogg, MP3, etc.)
passionato.com classical music, FLAC, MP3
hdtracks.com multiple genres, FLAC, AIFF, MP3
beatport.com mostly electronic, dance, etc, MP3, MP4 and WAV
junodownload.com multiple genres, MP3 and WAV
zunior.com/ indie, FLAC, MP3
mergerecords.com/ FLAC, MP3
matadorrecords.com/ physical, FLAC, MP3
audiojelly.com/ Dance music, MP3
8bitpeoples.com Artist collective
Free music (as in gratis)
jamendo.com/en/ Creative commons licenses, mostly. Free to download and listen to at any rate.
frostclick.com/wp/ Creative commons, portal links to P2P and other sources. 100% free and legal.
Thanks, guys! Feel free to suggest more!
