To this day, my most hated song that I've ever heard overplayed on the radio is "Hey Soul Sister" by Train. I completely loathe everything about that song. "Starships" by Nicki Minaj is a very close second.
Those big hit youtube songs like Gangman Style, Harlem Shake, and What Does the Fox Say. They're good the first few times but it just gets so tiring after the next few times... and annoying.
Also Taylor Swift songs from 2012 to 2013. Ok, so you broke up with a guy. Do you really have to make multiple songs about it?
I'm friends with a few people whom I only hang around because they're unintentionally hilarious. Sometimes they can be boring or annoying, though, so that's when I wonder why I'm friends with them in the first place.
I clicked a button for four hours and was ranked #2 on the AFD leaderboard until I came to my senses and went to bed. Amazingly, I've done less productive things before.
It was a button for April Fools. Thanks to that thing I went to the one place no one would think of... the Programming Forum. I also went to the old legacy comments and got many there.
