Most of the stuff I learned to play, I learned in high school. I had a band in high school, a jazz-fusion thing, and I was the keyboard player. I was interested in how the instruments worked and the theory behind playing with them.
Actually, if I could deliberately sit down and write a pop hit, all my songs would be pop hits! Let's put it this way. I play what I like to hear. And sometimes I like to hear something poppy, and sometimes I don't.
