I've had a Zune Pass for going on two years now and I must say it's fantastic, especially when used with Bing Audio search on Windows Phone. You just let the phone recognise a song, and then press download. It's seamless and there's no switching between apps. The Zune software for PC is fantastic too, my Apple fanboy friends always look envious when we're partying at my house. I've never really bothered with it on 360 though, because I just use that for games.
