The 7Digital Music Store app is kind of neat. You can stream and download all of your purchased music and even pin artists, albums or playlists to the Start screen. Seems cool. I wonder why this isn't implemented in Microsoft's own Music app.
Pinning albums to the start screen is a nice option but I bet not something many think of doing. In the end it just adds to the mix of all the other things you have pinned that are probably more important.
