When I Was Your Man & Roar are the only ones that I don't like
Harlem Shake & Just Give Me A Reason are just OK.
The rest is just amazing
Royals is the best
My bottom 3: 1. Harlem Shake - I mean, it's just a beat. 2. Blurred Lines - The most overexposed song of all time. When it came out, it wasn't all that anyways. 3. When I Was Your Man - Great song, but just the third weakest of these.
Top 3 would probably be Locked Out Of Heaven, Roar and Wrecking Ball.
