I think the biggest, most awesomest one is happening on Cinco de Mayo -- Donald Glover is hosting while his alter ego Childish Gambino is the musical guest. Like HOW FREAKIN' AWESOME IS THAT?!
But the final 2 episodes after that are pretty stacked, too!
Amy and Kacey should be solid since Amy is hilarious and Kacey can sing her purdy lil face off, but I'm PSYCHED for Tina and Nicki -- I have this unspeakable attraction to Nicki that I can't even understand, plus she's awesome, so...LET'S GOOOO!
