I shouldn't have read this thread.
Of course I had to download the Cheeky and Ketchup songs... just to see what everyone's talking about.
I know I may get shot for this, but the one song that drives me nuts these days is Clay Aiken's 'Build Me Up Buttercup'. It's one of my favourite songs and he over sang it far too much to suit me. I've tried listening to it again (God I love kazaa) but I just can't get over it, nor can I forgive him for ruining my happy song. *shakes fist*
