"Make a custom All Star (by Smash Mouth)! Add a sound in, replace "uhh" block with your sound in the "Note" custom block, and you're finished! Quite simple, really. I recommend having a sound that is 0.3 seconds or less, or else it will sound weird lol (and also one syllable)" - @Rae-TV Notably, the timing of @Rae-TV's notes were slightly off. I fixed all of the errors, so that the tempo is nice and even and you should be able to layer in a backing track with no problem! If you see any errors I forgot to get, just tell me and I'll try to get them fixed. somebody's probably done this before but lol idc Idea and original project by @Rae-TV All Star is by Smash Mouth
