11th Performance - Pentatonix - "Since U Been Gone" and "Forget You" Remix - Sing Off - Series 3

Normally i like their mix of songs whenever they do it because they always sound so versatile but i wasn't a big fan of this one to be honest..it sounded like the singers were tired, maybe it's because they had to sing right after the opening performance, but the other thing i didn't like was that it was too fast compared to the originals. They're still on the way to victory but this is just one of their weakest ones for me. B

they sang "Since U Been Gone" by Kelly Clarkson and "Forget You" by Cee Lo Green
