McClure said that artists such as Allen, Muse and the Featured Artists Coalition were hypocrites for making "millions of pounds" yet still complaining about illegal downloading.
He told The Sun: "We've got Iraq today, Afghanistan, bankers are taking the p*ss, MPs are taking the p*ss, BNP are on the rampage, plus we're melting the ice caps. There's a lot to be angry about but nobody wants to do it.
"What upsets me is last week Lily Allen and Muse came out and said, 'We've got to campaign against filesharing. We're having breakfast with Peter Mandelson and we're gonna tell him to shut down kids' internets'. Now, what a crying shame it is that all you can get angry or upset about is kids nicking your music.
"The thing with Lily is, I think when you get your nipples out in GQ and you're trying to make serious political comment with the government, you're putting yourself in a silly position."
He added: "At the end of the day, I stole Lily Allen's album and there's nothing she can do about it. People think I'm a communist because I've got these views, but I'm not. I'm not saying people can't earn a living, but let's be fair.
"Muse, you're playing Wembley stadium, Lily Allen, you're playing arenas. You've got millions of pounds, there's things happening that are far more important than that. The thing with music now is it's all self-preservation. Of course you don't want kids to nick stuff but they're doing it all the time and good luck to them."
