Almost all music of Sonic the hedgehog 3. There are no title screen music, invisible music and Knuckles theme. (and no multiplayer zones) You're really stupid if you don't already know what to do (just click them). Well and there aren't special stage too.
Music by Sega, and found on scratch by FreeSoundsProject. Use if you want. Sonic & Knuckles music here: https://scratch.mit.edu/projects/467489729/
