Do you want a colossal amount of free music? These are torrents containing a track from each band at the annual SXSW film, which is held in Austin, Texas every year.

If you don't yet have torrent software, I recommend utorrent. Yes, it's legal to do this, don't worry! I do this every year and pick out my favourite tracks, make a CD and enjoy it for a good long while.
