While the video in the top spot may be a little surprising, the rest of YouTube's most-viewed videos are pretty predictable -- and it's not at all surprising that record-breaking artist Miley Cyrus is on the list twice.
The controversy surrounding Robin Thicke's not-suitable-for-work video for "Blurred Lines" helped drive it to the top of the list, while Katy Perry's intense PR and marketing drove views to the much-anticipated video for "Roar."
It deserves to be noted that YouTube separates viral videos from music videos; "What Does the Fox Say" and BadLipReading landed on separate lists.
Here are the top 10 most-viewed music videos on YouTube in 2013:
- PSY - "Gentleman"
- Miley Cyrus - "Wrecking Ball"
- Miley Cyrus - "We Can't Stop"
- Katy Perry - "Roar"
- P!nk ft. Nate Ruess - "Just Give Me a Reason"
- Robin Thicke ft. T.I. and Pharrell - "Blurred Lines"
- Rihanna ft. Mikky Ekko - "Stay"
- Naughty Boy fr. Sam Smith - "La La La"
- Selena Gomez - "Come & Get It"
- Avicii - "Wake Me Up"
Meanwhile, across the pond in the UK, Naughty Boy takes the first spot, and Thicke outpaced Cyrus, bumping her down to numbers four and five.
