Napster v. iTunes

I myself have always been a loyal iTunes user. The only complaint I have against iTunes is the same one I have against all Apple products, they're hard to get in a compatible form. Specifically if you have Microsoft. Napster has basically the same features. However, Napster isn't compatible with iTunes, it has fewer features, and mediocre streaming sound quality. iTunes has it's downfalls as well. Price being the biggest factor, followed by, no subscriptions and it's processor intensive. Between the two the differences are pretty minute. Forced to choose one, I'm very picky about sound quality, so I'll stick with iTunes v. Napster. I also don't download music that often, so I'm not particularly interested in subscriptions.
