Well to start there’s way too much energy in the mid frequencies around 500 Hz, and not nearly enough in the sub bass region. That’s one really common trend I’m noticing from a lot of people who got rejected. You have to fill up the sub region especially during the main sections of your track. Not just kick drum, you need bass too and it needs to be balanced with the rest of the frequencies. This can be accomplished by taking a spectrum analyzer and looking at your track vs. other professional quality tracks and noticing the differences.
Right now you have a bassline that 1) doesn’t really match the chord progression played by the synth, and 2) it’s so sporadic and inconsistent that it doesn’t drive the track forward and instead leaves a ton of empty space.
Also your track is audibly distorting… only several seconds in and I’m hearing distortion. That’s pretty much an automatic rejection if the listener can hear the effects of clipping or limiting or whatever you used. Doesn’t matter if the rest of the track is perfect, if the reviewer can hear distortion then it’s not going to be accepted.
So in conclusion my recommendation would be:
1 - Use an EQ to cut at 500 Hz or so from that main chord synth, 3 dB at least if not more.
2 - Replace the bass you currently have with a bassline that actually matches the chord progression and have the rhythm be consistent and not cut in and out leaving huge gaps.
3 - Choose a kick drum that’s less boomy and with more of a transient so it can cut through the mix a bit more (personal preference really but your kick is kind of muddy and doesn’t have much clarity compared to the rest of the drums)
4 - Make sure there is absolutely no audible distortion. Not sure what’s causing the distortion right now but whatever it is, find it and fix it.
This won’t guarantee the track will be accepted of course but it would go a long way towards improving it. Either way I wish you luck!
