Regarding the mention of creative commons licensing, I want to add some personal experience:

In the same sense that great music software like BIAB enables an unprecedented number of people to create awesome music... similar software for film making and animation has resulted in an explosion of video. That spins into a need for royalty free music, and lately I have seen a LOT of indie film makers and hobbyists using music they've found on youtube that has been made available for free use under creative commons licensing arrangements.

Following the name through youtube searches, it becomes obvious pretty quickly that a cool song will get used in a lot of videos pretty quickly! If each one of those videos mentions YOU in the music credits... that's a whole new group of people who now know about you, many of whom will put you in THEIR videos etc etc.

In the same way that people who got in on the ground floor of something new benefited more than those who jumped onto the bandwagon at a later time, be aware that this marriage between creative commons music and film isn't new, but it *IS* just now taking off. It's still a good time to get involved.

Cinematic style music is probably the easiest to move, but there is always a place in movies for love songs.

my 2 cents. FWIW, I participated in an animation video contest last week. Pretty much all the music in all the videos was creative commons.
