Because Perfect Harmony shouldn't just belong to the hets (even though it's obviously Julie and Luke's song) Movie/series: Julie and the Phantoms (Netflix) Song: Perfect Harmony (Julie and the Phantoms)
I honestly would like a love song duet between Alex and Willie, would be really cute. Sort of romantic like Troy and Gabriella/Luke and Julie but playful and flirty like what they did with Ryan and Chad the song I Don't Dance from Highschool Musical.
