We’ve now got one less, one less problem — there’s finally an a cappella version of Ariana Grande’s ‘Problem,’ and Pentatonix completely smash it!

Thanks partly to the appearance of the Warblers on season two of ‘Glee,’ and partly to NBC’s talent-packed show ‘The Sing-Off,’ we go a little nuts for all things a cappella. Combine that with the awesome force of Ariana Grande, and it’s no wonder we’re already obsessed with Pentatonix’s cover of ‘Problem’!

The five-piece group performs every part of the hit song — instrumentals and all — in their new single. Their arrangement is impressive, their vocals are spot-on, and both totally explain how they took the winning spot in season three of ‘The Sing-Off.’

If you love their cover (as you should), you can preorder their upcoming EP ‘PTX, Vol. III,’ set for release on Sept. 23, and receive a download of ‘Problem’ right away.
