Thanks for the feedback, I agree the kick it’s a bit unusual but if they only accept from now on 4/4 beats with the kick on the root then this site will soon “sound” all the same and boring.
I always try to make something different with my songs, maybe it’s too much, but they are contradictory in their statement for Authors: “We encourage originality” they said… anyway I sent a ticket requesting more feedback.
Btw, if the mix is the problem as you pointed out (and they give me that explanation) the track could be soft-rejected and then I could do something about it to fix it… We all spent lots of time composing and arranging our music, at least they could give us a chance to fix things if the song has technical issues by giving REAL feedback.
Thanks again
