Hey, thank you for sharing your site. I think that overall it looks like a good beat selling website!
One thing that I would change is the yellow color of the beat player, because this makes the white text extremely difficult to read. (Or you could keep the yellow color of the beat player and change the text to black).
I might also add a section that has some sort of info about yourself such as a picture/video and production credits or musical experience.
Overall, I like the website, it is simple but straight to the point with no BS.
