Control tempo, key, and rhythm when creating a song

I would really appreciate a fully reliable way to control tempo and rhythm in Songer AI.

I produce music for many dance groups, and for this purpose, both tempo and rhythm are absolutely critical in determining whether a track can be used or not.

One of my biggest issues is with tempo—especially very slow tempos. For example, I am currently unable to generate songs below 70 BPM, even when the prompt clearly specifies something like 55 BPM. I strongly suggest adding a precise input option for tempo, such as a dedicated box where users can enter an exact BPM value.

Rhythm is my second major concern. So far, I have not been able to create a proper Rumba track. Songer usually generates a Samba instead, which is completely unsuitable for dancers who need a Rumba. For dance applications, this distinction is essential, and getting it wrong makes the music unusable.

I would be very happy to see a feature that allows users to define rhythms accurately and reliably.
