Aphex Twin wouldn’t be accepted here either (with almost 3 million Spotify listeners and hundreds of millions of streams, if not billions, on music released long before Spotify was a thing)…
They just think your track is too experimental. Sadly, they are still stuck in the “ultra cheesy generic commercial with zero creativity” prison, despite declining sales.
I think the track is pretty good, so keep it up, release it elsewhere, and for now, I suppose try to make more generic stuff for this site (and likely no sales on those new tracks either). 
Hello!!!
I express my opinion about this work. Excuse me for being blunt, but this item has nothing to do with music (there is no arrangement). Now about the sound quality. The sound of the track is muddy, indistinct (with the exception of percussion marimba). Space is flat, there is no depth. Nevertheless, dear Dreadwolf, do not despair. Try to comprehend the process of arranging and mixing. Sorry for my English.
Good luck!!!
