Since 2005, I have supported the annual South by Southwest music festival by operating a "seed" for the BitTorrent files they have created. From 2005 through 2007, SXSW created the torrents themselves and hosted them on their own tracker. I learned that this year, for whatever reason they won't be doing that for us.
So, I took matters into my own hands (after all, the songs are all available for download) and have created a torrent of the 2008 showcasing artists, which is one .mp3 file from 764 different artists. This year, it is almost 3.5 GB of new music, for free.
(I noticed that the torrents for 2007 and earlier are not currently working. I've emailed a contact at SXSW and we should get those restored soon, otherwise I'll find another way to make those available again.)
