As the title suggests! Are there any bands that you really can't stand most of the time, but they have just one song that you inexplicably love?
Most of mine involve dull, landfill indie bands:
Somewhere Only We Know by Keane
El Salvador by Athlete
Golden Touch by Razorlight
Under the Bridge by Red Hot Chilli Peppers
I was going to add something by U2 but then realised that I like at least five of their songs, so evidently I don't hate them as much as I thought I did 
One hit wonders don't count, btw!
