Everything is just floating there. It just looks very unfinished. And I really think you need to make a distinction between, "simple," and incomplete.
The text is also all over the place. One moment it's very professional looking, the next it's some cartoon shit. The text on the left side is also very small, and very hard to read. Not to mention the fact that you have everything put onto one side or the other, than at the bottom you have this huge ugly link that says "Watch Videos," which is about triple the size of anything else on the page, and just sticks out like a sore thumb.
Then when you click on one of the links on the left, it just takes you to another music player that is even uglier. Why not just have those link to videos, instead of ANOTHER music player? Just seems like a waste to me, and you could reduce clutter on the main page.
I don't know. Very unfinished, very clunky design. I'm not a fan. And please, don't take anything I say here personally. I don't mean it like that in anyway.
