After signing a deal with the devil, A young egotistical successful musician must get out of his leech music executive’s contract in order to be with the love of his life, and gain back his freedom.

Dude I just looked that film up, and its crazy I never heard or seen of that before, and strange as it is the summary is almost exactly what I came up with...for my idea lol and I didn't even realize it wow.

Thanks for your help, it did gain me some inspiration to get what I'm trying to convey, I can't thank you enough :) I will keep working hard crafting this.

Leaning towards:
“An egocentric musician must escape an enigmatic music execs contract when signing his soul to the Devil”

I left the B story (love) out, make this yours, keep going!
BTW: check out the 1984 classic “Oh, God! You Devil” for research.
