Is it just for use on forums? It looks cool, but is a bit generic and doesn't really show others what it stands for. Maybe add a small graphic of your niche, in your case maybe a few music notes or some speakers or something to do with music and sound to give people the idea of what your site is about.
The colors and style look fine, but you might chop off the www. part so you can increase the size of your domain name. I agree with Powelly and think music notes would be a good addition.
It looks nice, but I agree with the others - make the font bigger and more readable By the way, are you still having trouble getting it indexed or have u got it in now?
Thanks for the follow up, Im indexed about 8 times: http://www.google.com/search?hl=en&q=site:sounddistrict.com&aq=f&oq= Rep added ++++++++++++
By looking at that all i can see is 'SD' which means nothing to me. It's hard to know what it is you're trying to market.
the url is a bit hard to read make it Site.com now www.site.com or remove the www and the .com if you have that page in google if searched
The URL can be hard to read. It makes the avatar kinda unclean, if you are getting my point. Plain SD doesn't seem to give me an incentive to join, and I'd probably be looking for a better avatar.
