The site doesn't seem to agree with my computer - froze at Jimi. Which is as well, because I can't stomach Jimi being labelled a one-hit wonder. ;)
I remember reading a similar list a while ago though - of genuine one hit wonders and, also quite interesting, a list of chart toppers who'd filled for bankruptcy, among which, the Goo-Goo Dolls.
Hard to conceive that you be left w/o a penny after writing a hit like Iris...
