This isn't directly answering the thread, but is a tip my son showed me. Basically you can use spotify exactly like how itunes used to work, and use it as an interface for playing all your local mp3s... I've been looking for something that would do this for ages, and it is a good interface. Of course you can only listen on the computer that your linked mp3s are on. But also you could make playlists that use your local mp3s mixed in with the streamed ones etc... I find it very good for computer listening.
