Distribution question for the band

[mondokat]

I know underworld reads this, so I thought I'd post a question to them (although you dirties are free to respond, as well).

Basically, I was wondering what Underworld thought of the fact that every time there is a radio show, someone rips it, splits it into individual tracks (or leaves it as a big mp3 of the whole show) and posts it somewhere for download. Obviously there is a huge demand for these things to be distributed in a more static fashion (non-streaming).

Why doesn't underworld post the listen-again's as mp3's instead of streams and save us all a step? I understand there's bandwidth to be paid for, but if the rtsr tracker is anything to go by, bittorrent isn't an issue for most dirts, so underworld could just host a tracker and be done.

Is there some sort of legal re-distribution issue with the third party music?
