What is the best and most sophisticated music program for pc?

I know similar questions have been asked before here, but I'm a little more specific. I'm in the process of making my first indie video game for the next E3. I want the best music software so that I can make music like Kingdom Hearts, Blinx, Sonic, Ratchet and Clank and so on... so there is a wide range of different types of music I need to be able to make and make well. Anybody got any suggestions? I'm trying to get what the pros use. Thank you!
