Hey
Well, my friend told me that there was a song that was over two months long, made by a noise band called Bull of Heaven, so after a quick google search, I found their website. Turns out that their song "The Chosen Priest and Apostle of Infinite Space" (Number 118) is 1453 hours long!

Just thought I'd share. And I'm wondering if anyone has that much patience and dedication to freeup a 100+ Gigs of space to listen to Bull of Heaven for a few months (or a few years).
