What is the most annoying song you have ever heard?

For me, that would have to be each and every single song from Nicki Minaj. I really can't choose just one...all grind my nerves an equal amount... >.<

Super Bass and Blurred Lines. Take your pick.

Top 6
1. Ariana Grande: Problem
2. Robin Thicke: Blurred lines
3. Lorde: Royals
4. Megan Trainor: All about the bass
5. Taylor Swift: Shake it off
6. Sia: Chandelier (in this case the video annoys me even more than the song itself)
update! I forgot Sam Smith: Money on my mind

1. Gangam style.
2. Hangover.
