I also get only hard reject. The problem with this is if the track has a problem with instruments or drums or anything else we could just improve it then submit back. But if they give us just hard reject it means just one simple fact - our music is not even getting close to what they need.
But I think they have to much work, so they won’t bother with this kind of tracks. So my advice is to submit until you get it right.
Try to get a video advertisment from youtube and see if you can put your music over video, if is working then you have a chance to get approved
I understand that they don’t have time to write for every author a review, this is just impossible, but for some track they could do an exception and give it soft rejection.
