I have a fairly wide and eclectic range of musical tastes, but I think there are one or two that I might class as guilty pleasures.
As for things that I actually like and would choose to listen to, I think
Teenage Dirtbag by Wheatus is probably the one that might be considered the worst.. cheesy as hell but damn I love that song XD
Anything off the Darkness' album Permission to Land, again so cheesy but great.
This is my favourite :)
The Kooks - She Moves in Her Own Way OPM - Heaven is a Halfpipe There are other songs that I wouldn't choose to listen to, but find myself singing along when they come on the radio (and hating myself for it)
Anything by Taylor Swift... as much as I hate it, she makes catchy music.
Cheryl Cole's song I Don't Care
I think it's interesting to see what others think of as guilty pleasures as well; Sinatra, Abba and the Bee Gees? If we're classing things like that as guilty pleasures then half my music catalogue is probably guilty pleasures :D
