— -- Michael and Carissa Alvarado, a talented husband and wife team known as “Us The Duo,” popped into “Good Morning America” today to perform a mash-up for us live on air.

A video of the couple singing the hottest songs of 2015 in just three and a half minutes has racked up more than four million views on YouTube.

The Southern California duo sang their renditions of One Direction’s “Drag Me Down,” Nick Jonas’ “Jealous,” Fifth Harmony’s “Worth It” and Taylor Swift’s “Bad Blood.”

With such a fun-filled year in music, they say it wasn’t easy choosing which songs to include in their short video.

“It was really tough for us to pick and choose which songs we wanted to put in this 3.5 minutes of time, but we just Googled the best-selling songs of the year and we kind of chose from that, and we listened to our followers and what they wanted to hear,” Carissa explained.
