nice moodsetting! but your beat seems out of sync every 3'th & 4'th beat. did u put 2 beats on top of eachother? cause that could be the problem. also give a look to your higher frequencies: the hihats are very silent. boost them up, cause it makes the song rather blurry (no edges). and that melody from the beginning is badly cutten: you actualy cutted the sound in the middle of a soundwave, so you get those "clicks". put a very short fade in and fade out on those cuts and that problem will be solved.
