what is your favourite AI music generators for beats especially?

I tried suno. ace step XL and heartmula (please share if there are any good alternatives), my goal is to have good beats for rapping like anime beats or any famous rap type beats. we can train Lora for sure but what is the best out of the box AI that can get the Job done. and yeah, I even tried the latest Google Lyria 3 music generator, pretty good but still not able to generate what I have in mind, and I am sure it is the case for all of us. might be its prompting, please share if you guys have found any good prompting format or template to get the best result.
