Taylor Swift, Katy Perry and More: Watch This Mashup of 2014's Biggest Hits!

We could watch this video over and over.



From Taylor Swift's "Shake it Off" to Pharrell's "Happy," there have been a ton of songs that we've fallen in love with this year, and they're all in this awesome mashup.



DJ Earworm's annual "United State of Pop" music video hit this week, with the music maestro telling Billboard "Do What You Wanna Do" was his most "challenging" and diverse mash-up yet.



"The thing that has been most notable in the past two or three years is the decline of EDM," Earworm told the mag about the 25 songs he selected for this year's video. "The 'United State of Pop' became this dance track from '09 to '12, and then starting last year, there just wasn't enough in that genre to fully support it, so I went down-tempo."



The DJ added that 2014 was "dominated by these slow, ponderous songs like 'Say Something' and 'All Of Me,' and then swaggering hip-hop songs like 'Turn Down For What,' 'Talk Dirty,' and 'Black Widow.' Then you have totally uptempo songs like 'Happy' and 'Shake It Off,' too. It's a little bit more diverse, and definitely softer than it's been."



Earworm first released his annual mashup back in 2007. This year, he seamlessly weaved together John Legend's "All of Me" with Iggy Azalea's "Fancy," Jason Derulo's "Wiggle" and so many more hit songs. The video is about four minutes long and kept us glued from start to finish.
