Due to popular demand, I’ve made available torrents for each volume of mashups on the Tunes page. I am uploading this from my own connection, and I can upload up to 245kB/sec, so it may take a little while for more seeders other than me to happen and the speed to increase. Enjoy!
Update: Due to too many leechers and no seeders, I’ve stopped providing these torrents. I gave the torrents to others, and they had the same problem — too many hit-and-runners. Sharing 18GB worth of mashups just wasn’t working with people not willing to share after downloading a volume, or all seven. If you’d still like to download all the mashups, head on over to the Mashups page.
