Going into the music business need help!?

am starting a record company with a business partner, and in all actuality he is providing most of the monetary support for our work. I on the other hand create 90% of the music we put out and am the creative force behind our projects. I am in the process of coming up with my end of our deal as business partners (i.e. % of the company, what i would want in the event we liquidate etc etc) now my question is how do i make it so that in the unfortunate event of us liquidating the company, do i keep rights to the my created work and still maintain full usuage of the music, i.e. performing selling or distribution thereof the work? and also if there are any recommendations or advice someone can lend me for my situation. my biggest concern is his advantage of having more money than myself. any advice will help.
