There are lots of ML models that produce instrumentals and vocals that are incredibly useful for practicing musicians.

The popular and well-known Suno and Udio are pop culture toys. They also find use with content creators who don't have time to learn how to make music. (Not everyone can learn and master everything. We have to let some of our creative desires slip or we'd never be able to accomplish anything.)
