I don't think it particularly helps or hinders musicians. You don't see 50 Cent making TV adds decrying the awful poverty he is currently living in because of piracy, every artist in the business seems to still do bloody well out of the industry.
A fair amount of the time the reason why people pirate music in the first place is because they can't afford to go out and buy a ton of albums, so even by stopping the piracy I can't see music profits greatly increasing because it still doesn't mean people have more money.
I'm slightly undecided on the issue as I see it as being akin to lending you mate a CD, and them ripping it to their PC, just you have a lot of friends to lend you CDs.
