The problem with this one is that I tend to listen to almost every single musical genre, so it's kinda hard to think of something that would surprise people. I did get a raised eyebrow from a friend when I bought an Enrique Iglesias album, but that friend was unaware of my love for ridiculous Latin pop.
However, I think I nailed it with this one:
"Jumpin Jumpin" - Destiny's Child There is nothing musically outstanding about it; the lyrics are shallow and repetitive; I've never cared for Destiny's Child because it was only ever a way for Beyonce's dad to showcase his little girl. They weren't bad, they were just a useless pop group with members who were disposable if he thought any of them might be upstaging Beyonce.
