Meat Beat Mania: Over Easy makes its appearance in "Arcade Mania" when Garnet starts to play Meat Beat Mania and it is on the easy stage. It has a relaxing feel, and what sounds like a trumpet added to that.
You can listen to the song on Aivi and Surasshu's Soundcloud page. They also created Steven's Shield, Lion's Theme, Peedee's Blues, and many other Steven Universe songs.
