Okay
Well the beginning sounded like a space ship sound effect, and didn't really match the song that was about to play. The bass line is really boring and repetitive, as well are the drums. The piano doesn't sound good at all and there are totally awkward parts in the song that just don't sound right at all.
None of these instruments agree with each other at all, and I think that is the fundamental basis for music. That would be my main problem with this song. Nothing blends or sounds like it belongs together at all.
It almost sounds like all the instruments are just doing totally random things and random times, and it usually gets left with just that repetitive bass line playing in the background by itself with a repeating hat riff. Doesn't sound good at all in my opinion and needs a LOT of work.
