What was the worst band or singer you’ve ever listened to?

There many songs that I hate more than anything by the Carpenters but they are the only band with bad songs that I've had the misfortune of listening to more than one bad song of. I can't stand the treacly, cutesy bullshit they put out.

I would also put the person who sang " ON THE WINGS OF LOOOOOOOVE" on here but I can't be arsed to look them up.
