Friendly critics requested to test a site (especially Drupally musicians!)

Over a year ago, I set up a Drupal powered website - FreshDynamics.net - to host my podcast, featuring music from unsigned artists & independent labels.

Previously, music was sent to me on CDs, but I've decided to start accepting tracks through the website.

I'd like to make sure that I haven't got snow-blindness, and that the interface for musicians to sign up and submit tracks for the broadcasts works smoothly.

If you have a few minutes to play with the site, please visit:
http://freshdynamics.net/user/register
and sign up as an Artist.

Once signed up, users can edit to their profile, and then click Add Track to add a track to their collection. You can press Help at any time if it doesn't make sense.

It would be great if anyone could try submitting tracks to the site. I'll presume you're just testing, so I won't include any of the tracks in a broadcast, but if you are an unsigned musician, then make a note in the track comments if you'd like me to broadcast your music.

If you're browsing the site, and can think of any cool modules that could improve the site experience, feel free to make a comment on my rough roadmap.

If there's anything that's broken, or that you can't understand, please do contact me, through Fresh Dynamics, through my Drupal.org contact form, or via comments below.

Many thanks to anyone who's able to give it a whirl.
