I made a webapp to generate trippy vidoes from your music for sharing on Instagram. Any feedback?

I made an MVP! It's basic, lacks a lot of features I want to implement, the code is a tangled pile of spaghetti, and now I want to shift focus to validating the idea to see if I should continue working on it.

I plan to use an Instagram account for marketing and generating interest by showing examples of what you can make: https://instagram.com/pasteur.cc.

Thanks in advance for any questions or comments!
