Pentatonix Puts Their Spin on Ariana Grande’s ‘Problem’ [VIDEO]

I love Pentatonix...and now I have one less problem. Our favorite a cappella group has released a version of Ariana Grande’s ‘Problem.’

Pentatonix is a 5-person vocal band from Texas that combines various genres such as pop, soul, R&B, and electronic music. They were the winners of season 3 of NBC’s ‘The Sing-Off.’
