'Tis the season for year-end mashups. Pop Danthology is leading the pack with a video that crams in 68 of this year's Billboard chart-toppers.
The nearly six-minute-long video features Miley Cyrus, Robin Thicke, Daft Punk, Selena Gomez, Taylor Swift, Lorde, Avicii and even viral hits like "The Harlem Shake" and Ylvis' "What Does the Fox Say?"
The video's creator, Daniel Kim, went viral in 2012 for his mashup that received more than 44 million views on YouTube. Kim writes on his blog that this year's video took more than 180 hours to complete.
So sit back, relax and take a musical walk down memory lane.
