Feedback on my music start up :)

To be honest, the site itself looks a bit amateurish -- weird or no padding in the text boxes, cut off tags that don't fit into the .tags div, usernames sticking out of the boxes (at least in FF on a mac), eg. http://songfountain.com/discussion/749

The Site Feed arrow is below the fold on the home page, so my first thought was I have to register to even browse the site -- you might want to promote the feed more prominently to engage visitors before you make them join the site.

Your tagline ("Song Fountain is the most effective way to discover new music!") sounds too much like a marketing claim, especially since the site doesn't look to be a major player and it's hard to believe it's more "effective" than last.fm or Pandora.

In the video you're describing the functionality of the site like you would in a technical manual. You might want to try to talk from a user's perspective ("How do I achieve this and that with Song Fountain?").

So there, that's my first impression. What are your plans about the site? Is it a side project (for fun, not money) or do you want to make it big with it?

In short: we all think creating a music startup is a fantastic idea, but it really isn't. :)

Also, the UI on the search dropdown doesn't make sense. You select a field to search, but then if you start typing in the box you can't remember what field you're searching anymore. Maybe you should just use a normal dropdown instead of rolling your own.
