what level should i go for next?

i recently beat b which is kind of the first level ive beat and i want to move on to something else but not sure what - i liked b a lot because it had good music sync, a good song and fun gameplay so i would want something similar to that (idm the difficulty as long as it's not a crazy hard extreme)

i tried verity and the majority of the level is easy, i just cant get the end in my head so i decided to js drop it
