Alternatives to iTunes for previewing music?

The only feature I use on iTunes is to look up different artists and preview clips of their songs to see how they sound. Are there any sites out there that do this and have thousands of artists in their database?

youtube.

google video the songs and chances are something will be up. That how I find new songs to make sure an album is worth it.

See: torrent sites

Their like itunes but they dont stick you with DRM, and low bit rates.

Don't listen to any of them :P Grooveshark is awesome.

Music sites in general have previews of songs. Lastfm.com and Amazon.com also have previews.

Last.FM and Youtube.

Youtube you can usually listen to full versions of the song.
