I'm looking forward to use Nokia Music service in my app, but I'd like to know what it can be used for exactly?

For example, I have a cloud music player that downloads music from user's cloud storage, allowing the user to save it to his/her music library or just listen from the cloud. Can I use Nokia Music APIs to display artist's images (if there are ones), show info about track, album, and show suggestions to buy another tracks from this album and/or this artist?

What others ways to use Nokia Music service could you suggest?
