Musicgpt doesn't do what you ask
Musicgpt can definitely create songs for you, but they most likely won't sound anything like what you want them to sound like. A request to make an ambient and meditative song returns an Asianesque song with cello, piano, drums... hardly ambient and meditative. A request to remix a downtempo electronic song in the same style returns a disco-like dance club song. It just can't accurately do what you want it to. Which is a waste of time and money.
