Feedback on new iPhone music app

Hey guys, I'm an indie iPhone developer and just finished my latest app. It's a music app that helps you find similar artists to what you're currently listening to, along with aggregating their bios, top songs, and music videos.

Here's the description from the App Store along with the link:

BeatSpace is a music discovery app that helps you find new music similar to the artists you already like. Listen to top tracks, read artist/band bios, view photos, and find music videos for related artists, all found using the similarity of the music you already like.
