I am a 17 year old rapper and recently got spotted by universal.?

I try and stick to my own style, i use quite a lot of explicit lyrics in my music and i myself will admit that my music is sometimes offensive but its got a underground following and ****, i went for a meeting with them this past week and they outlined where they wanna go with my career and some of it was swag but for the most part it was quite a ***** *** slave ***** contract, they wanted to market me as a kinda "black" justin bieber. I wanted to think it over and i wrote a track called "My ******* Universe" which i was about to drop yesterday in response to the contract but im starting to think should i just go a head with it and not listening to any of there demands or should i just **** them and release the track?
