I get the concept. WHere music is it's colred everywhere else it's black and white. But this concept would work much better on a landscape artwork.

The cutting is bad, honestly you need to learnt he pen tool if you havent alreayd and stop being slopy.

The effects aren't exactly fantastic either. The lines don't really make sense drawing your eyes off to the outside of the LP.

Finally the text coloring whats with that. I get you were tryign to make it colorful and kind of retro at the same time. But you can't color some lines and not the others. You should either do like 3 colors at most or 1.

Overall i think you are getting lazy and just pasting things together. You really need to work on pasting things up. Look at this style on deviantart and see what makes them work, how they do it, it will help you immensly.
