I Need Some Advice
 

I'm in a band, and I play the drums. We've been together like a year.
I can plays drums, guiter, and bass well, and can somewhat play the piano. I love the music I make, I make every instrument part, and over half of the band songs are my songs. They are all pretty original and the guitarist is saying that he's just doing them because I want to do them. The guitarist is doing songs that I hate because everysingle one is the same powerchords, just re-arranged. I have the ability to just record all of my own music that I want to do.

Should I leave the band? If so, how?
