If you can't remember all the hit songs you heard this year, consider this a refresher.
YouTube singing sensations Michael and Carissa Alvarado, known as Us the Duo, are back at it with their roundup of the year's hottest songs, an amazing video that mashes up hits from Nick Jonas' "Jealous" to Fetty Wap's "Trap Queen."
And, of course, the clip kicks off with what was arguably the year's most talked-about song: "Hello," from Adele.
Seventeen songs made the cut, also including "Hotline Bling" by Drake and Hozier's "Take Me To Church."
The video has more than 1.8 million views on YouTube and counting. The Southern California couple did a similar video last year, which incorporated hits like Meghan Trainor's "All About That Bass" and "Happy" by Pharrell Williams, racking up nearly 15 million views. Us the Duo, who became Internet celebrities after a video of the couple singing their own wedding vows went viral, also performed the 2014 mashup on TODAY.
They describe themselves as "just a couple of best friends who happen to be married and sing together."
