Chvrches are the most likely on this list, and with unlikely Danny Brown they'd be my favorite. Five not mentioned yet who I'd love to see:
1. Chance the Rapper, probably not big enough and without a huge single. (Juice and Chain Smoker)
2. Earl, could happen but unlikely unless they low on choices (Burgundy, Whoa)
3. Lorde, who is probably a very likely choice this season (Royals, 400 Lux)
4. Ariana Grande, who may have a shot after being pretty funny on Jimmy Fallon, (Baby I and Honeymoon Avenue if my dreams came true)
5. Portugal. The Man, almost definitely not big enough too unless someone was pulling for them, (Evil Friends, Hip Hop Kids)
Not surprised at all, but glad she's confirmed, always great in the sketches. Also she can walk now so that's cool.
