Disclaimer: I know zero about webite design.
However; I like the concept!
The home page felt like any other page for me...a little too busy with advertisements...
I clicked on social beats and felt like it has too much color.
On a side note, a different application was playing some african drums/rhumba beats for like 3 econds when I clicked on social beat and I thought it was your site and my reaction was COOL!!! You may want to consider that (I am not a fan of sound effects on websites but that felt like a perfect fit. I'd use it sparingly though.)
All in all, I'd give it a B+.
