System of a Down -- I hated them when I heard Chop Suey. I then started to like that song, then I liked Toxicity, Question and another one.
The Killers -- I hated Somebody Told Me, then it grew on me and now I find it enjoyable.
Trivium -- Hated them to begin with. Started to like Pull Harder and found myself enjoying their album.
The Darkness -- I can admit I used to take the piss out of them all the time, but then I realised they were like a modern classic rock.
Foo Fighters -- I'm in love with the song Best of You. I can now sit through most FF songs, whereas I couldn.t.
Jimmy Eat World -- I just didn't like them then I started to like The Middle and another song they did.
Linkin Park -- Absolutley despised them at one point. Then I got into Numb, and voile, I enjoyed them.
My Chemical Romance -- Took the piss out of them too, then listened and liked Helena, Im Not Okay, Demolition Lovers and Ghost of You.
The Offspring -- Cant Repeat, I love that song. I used to always consider not serious, but yeah. They're quite good.
White Stripes -- Seven Nation Army and Blue Orchid are two of my favourite songs right now. I used to turn the channel over when they came on.
Velvet Revolver -- Same, I used to hate them 'cause it was a 'Sell Out' kind of thing with GNR. Now I wub 'em.
