@Aiparon-- LimeWire only gives you viruses if you're stupid about using it. Be careful about what you download, and don't use it often...
And LimeWire in itself isn't actually illegal. It's just the downloading of copyrighted material (which is probably 99% of what is downloaded) that is illegal. If LimeWire were illegal, it wouldn't still be up for download. XD
(Oh, and some artists offer to let you download their music off of MySpace, but you'll only find that with indie bands trying to get their music out there...)


Anyway. There is no free, legal way to download (most) music. Get either a torrent or P2P client if you want music, but be warned that downloading copyrighted material is illegal.. -cougheventhoughwealldoitanywaycough-
Project Playlist is the best way to go. They've got tons of music and you can make playlists! iMeem has recently become a piece of shit, because they made every song they didn't have a copyright on into a 30-second clip. Urgh.
