This is an internet radio app similar to Pandora , but with a few different approaches. It accesses your Last.FM profile [tatianamik]. You can pick radio stations based on your library, your friend’s listens, or recommendations for you. It also keeps your most recently listened to stations handy. If you simply just want similar artists it will handle that as well as artists that have been tagged. You can access your Top Artist, Albums & Tracks charts. When you are listening to radio you can look up the artist’s bio, similar artists, upcoming events & more. You can also share with someone in your contacts or among Last.FM friends. It also had the ever convenient Buy on iTunes button.
If you want to use the My Library function you probably want to be using the desktop version with your iTunes. It’s free from the website.
