And why is it the worst? What makes it bad?

To be honest, I'm just trying to get you all to do my uni work for me. I'm doing a music perception module, and I have to go a little deeper than just saying "because it's annoying and I hate it".

It's interesting though, because clearly one person's "worst song" is someone else's favourite.

I'd probably go with one of those horrific occasions where Christina Aguilera tries to impress us with her warbling. Goes right through me.
