I'm talking guitar, bass, or piano riffs that annoy you. Even if they don't necessarily suck, maybe it's the melody, tone, or what it's associated with..
I'm gonna start with "Seven Nation Army". Not because it's simple, but because that melody line annoys me to no end and repeats itself so much. I think the Baltimore Ravens crowd ruined for me even more. I also was in a cover band at one time and I was forced to learn the song, which I boycotted later because I hated playing that riff..
Any thoughts?
