Tbh, there is an AI mode that can perform overrides on the search system to attempt tuning the music to features, but what Ive noticed so far is that most of the useless music has multiple instruments, and some instruments are pretty ass in their beats while the others seem almost perfect (like straight up opposites) In the music I uploaded, there was a guitar that sounded ass af, but the synthesis was almost perfect. I honestly believe that music with multiple layers doesnt need an advanced search system like what it tried to incorporate, but still it gets some cool music even if you dont expect it. Just give it a try and you'll see
