Well, this is only a stupidly simple, lazy and shitty mod that is adding music to FU's music player, done in 10 minutes. Nothing that can be called disgusting. I mostly have done them just for myself and my friends, but when I started to add a few ones just for testing the waters and I found out some people enjoy them too.

Maybe it's bad in your eyes, anything weeb is bad. So if you hate this kind of content, why are you there, just to suffer and say animu is bad? Maybe find better things to do in life.

Hmm, maybe you should try modding Starbound? It's a really fun experience. There are mod templates made by Dr.Skittles that can be the base for your mod or read Unofficial Starbound Modding Guide E-book to learn some basics of it. Maybe creating something would be much better for your ego and mental health, than writing random hate comments on the Internet.
