Whilst I completely disagree with sharing of underground releases like this and totally agree with getting them to take it down I don't think you can ever equate number of downloads with cash. This mistake is certainly made in every file-sharing legality discussion. Surely out of those people who downloaded, if it cost them to download:
- some wouldn't dl due to cost
- some wouldn't dl because they didn't like the preview clip or don't want to take the risk
- some would pay and dl
- some would pay or buy the vinyl even though they had downloaded illegally already
plus there may be some reduction in numbers due to multiple downloads from the same person.
This discussion has already taken place many many many times before as to whether file-sharing harms music. My opinion is it harms underground music which is most likely to be internet based (and therefore shared copies are imminently available) and not so much commercial music (which is largely shop based - and I'm including iTunes in this as a 'shop' as it is user friendly and has copy protection built in). But I don't believe that 601 = £474.
So, er, don't worry too much about it?
*edit - but yeah, do try and kill them...
