We have 1 more year with Steven Universe until their final year which will be 2018. Season 5 will most likely to be Final Season so who should be the one who sang their swan song?
Swan Song is like FINAL song by some artists like Freddie Mercury for The Show Must Go On! Or David Bowie for Lazarus!
So who should be the one to sang THE VERY FINAL SONG! To end the show?
