@ OP, here's my 2cents worth.. Next time, purchase non-DRM'd material..Even iTunes sells them these days..
Why would any law-abiding citizen, purchase a gun and find out later that you couldn't take it to the gun range, hunting, or for home-protection..I mean, really?.. Back to the-music.. we purchase "the right to listen to them" and I/we want to be able to play them on all players, and burn them on a disc, for our own use..We all do it..Well, at least most do it responsibly..
Also, you might want to try out better(IMO) media players..foobar2k, Winamp, MediaMonkey etc. etc..
Cheers, and good hunting, err I mean, good luck with the-music!!..
