Opened the games, got my ears assaulted, ran to the options and got owned :') Honestly though, I enjoyed the sounds matching up with key hits and the music worked well with the silly aesthetic.
Rhythm games will usually have either the thing you're looking at be the "cue" (like rhythm heaven) or maybe have a break section where something happens on screen and you don't have to worry about pressing keys. I think incorporating something like that will let players admire your wonderful art!
