Your design is clean , you might want to add a couple more graphics to make the design a little more creative. It shouldn't affect your already awesome load time by too much and will give your site more personality.
Right now its just a cheap site I'm using with my adwords/adbrite testing. I'm going to get this theme eventually http://demo.wpzoom.com/?theme=videozoom As well as this program http://www.wppostgen.com/ as well as getting a nice logo made.
great site. you site design is good. I like your site design. I have already downloaded a song. But I think you should add a beautiful banner.
