I hate Neil Diamond's Sweet Caroline. Every time the moment it starts playing somewhere, or when I'm at a footy game, and everyone starts singing along to it, I immediately start ranting and throwing child like tantrums until the song stops.
Also this f*****g Jim Beam ad that shows up every now and then on my sports channels, I immediately start panicking and mute the TV until it finishes, if you any idea on how much I hate the song, there you go.
