I understand that you're targeting musicians, but to whom will you sell and distribute their music? The site doesn't currently mention or appeal to listeners. You probably don't (yet) have a lot of music to promote, but a quick visit to Beatport shows what type of attention is paid to audience and content.
Some initial feedback on the site's layout:
- The layout breaks at medium and narrow widths, particularly the home and FAQ pages
- Looks enough like Rdio that I feel compelled to mention it here
Good luck!
