Bit Torrents

OK. I confess. I am ignorant about this one.

Motts commented on my latest A Ghost Is Born post with a link to the Wilco tour opener. They were called Bit Torrents. I downloaded it and got a file but I can’t figure out how to play it.

The Jason Calacanis talked about working in his virtual office in Bryant Park with his headphones on listening to Howard Stern Bit Torrents.

I hate being ignorant. WTF are Bit Torrents?
