The lead vocals, not much in the way of hooks, stupid (ironic) band name, a sameness that runs through it all...just not my cup of tea. Their ubiquity probably makes my hate more than they deserve, but ***** it, they easily came to mind.
I also don't include any boy-band or pop singers because I'm not supposed to like them in the first place. These are acts clearly marketed to teens and younger. Hating on them is liking hating on Sesame Street because it's not as good as The Wire.
I'm going to type every word I know! Rectangle. America. Megaphone. Monday. Butthole.
