Music is also much more portable, and much cheaper. I used to paint before I left home, but I've never had the space to assemble a studio since. Without a studio, I can't just start working when the urge strikes me. By comparison, when I have my guitar or keyboard with me I probably play an hour or so a day. It's kind of like how, with a separate 'internet computer', you mostly don't go online by accident. The problem is that you need to doodle to make something as a painter or musician (or hacker).
The only time I've painted since involved jury rigging an easel out of a basement gym at the Princeton graduate college. I could take a class, but they're expensive.
Absolutely. I can't say enough good things about drumming: literally every bit of music I hear can become a collaborative (well, Karaoke-style collaboration) piece of shared expression. The only limit is the degree to which I'm willing to annoy the people around me.
