Hear Taylor Swift songs as you've never heard them before in a new medley performed by pop duo Timeflies. Producer Rob Resnick and vocalist Cal perform 'We Are Never Ever Getting Back Together,' 'You Belong With Me,' 'Both Of Us' and 'Love Story' wrapped up into a single tune.

The video shows Cal singing the mashup in the studio, backed up by pre-recorded guitars and programmed beats. Just as he reaches the chorus of 'Never Ever,' he shifts to the hook from 'Both Of Us,' Swift's collaboration with B.o.B. The video is the duo's latest offering as part of its Timeflies Tuesday series of covers.

We think Taylor would probably get a kick out of the performance. After all, she tweeted her approval of Hanson's recent cover of 'We Are Never Ever Getting Back Together.'

The Timeflies medley clip also features concert footage from the guys, who have dozens of gigs coming up around the country. During shows, they perform covers and their own material, and they have an album of original songs called 'The Scotch Tape.'

According to the duo's bio, Cal goes old-school when it comes to his vocal influences, naming Janis Joplin, Muddy Waters and Robert Johnson, while Resnick cites Benny Blanco, Pretty Lights and Porter Robinson as production influences.
