Generative Music/Song Maker

It will be very helpful if there is a generative AI music or song maker. For example, the user only has to type in the next chords, tempo, measure, etc. Just like royalty-free images generated at firefly, it will also be helpful to have a royalty-free generative AI song maker.

It doesn't have to have lyrics, the accompaniment will do. This way, musicians can just modify the generated song to tweak it according to their preference - just like generating a firefly image and tweaking it on Photoshop.
