Love the idea. My first thought is that the icon looks like an alarm clock.
Currently, the way I track album releases is by following every conceivable artist on Spotify, which will then notify me. What I like about this is that I can then stream the whole work, for free. However, Spotify doesn't always have works when they're immediately released. Additionally, I have to follow the artist in the first place--there's no library scanning. There's also the chance that I'll have work by an artist in iTunes but won't have ever followed/listened to them on Spotify.
In other words, could you also make a Spotify plugin which scans listening history, and combines this with your iTunes library?
May I kindly ask for Google Music support too, I use it and would love such a service. I was with rdio before, and getting notifications of new releases for artists in my library is what I miss the most.
