I used to use flocabulary and loved it when I taught all subjects. Now, since I switched to teaching art, I can't really use it anymore.

You should add art and music concepts to your library. As an art teacher, I know there is a TON of content to make catchy songs with. It can't be that hard!

Content like:

Color wheel

Warm/cool colors

Perspective

Color mixing

Art history (artists and movements)

Art tools

Art mediums

Street art (graffiti)

Proportion

Ceramics

Photography

And so much more!!!
