Sorry for not writing such a long review as last time, we'll see on your next song :P So yea, I like the song, but i think the problem is like the other people is saying, the bass is overpowering the rest of the song. Maybe a seperate compressor on the bass would let it as powerfull, but still letting the melody through. Also, reconcider some of the samples you have, as the downlifter/impact you have sounds a bit low quality. I like the melody, but the drop could have varied a bit more :P
I think some mastering a tweaking on the instruments and samples is all you really need on this song :) -Nemer
