Have you considered animating some of your older music videos (i.e. "new song: i can play")?
that never had a video but i would consider making videos for any of my songs. if i had time i would do it for all of them. i have done it for some of them. sometimes it's nice to make a brand new song with a video at the same time, but sometimes i make videos for songs after they were released as audio only. such as new canaan, movie star, tuesday, school, i like, and many more
