The bands that make one or two good songs in their entire career, and the rest would make your soul bleed if you listened to it for more than 5 minutes.
One such band, in my opinion, is "Breaking Benjamin". An otherwise very "emo" band, they made one song that I can listen to and NOT want to put a gun to my head to get the horrible music out of it... and that was a song for halo 2.
