Kurt was a phenomenon and rocked the world till it lasted. His songwriting skills debate will always be there, however, the question :is he worthy of rock 'n' roll fame : YES (he did had a noticeable presence and contribution)
is he worthy of a top 50 spot in 50 greatest "SOLOS" in the R'n'R history (they used the superlative there) ? unfortunately no , at least not at the expense of some other talented musicians (i hope we can agree that there have been some serious omissions from the list, in contrast to some of what's currently on there).
A better debate could be on -> who made this selection for the top 50 list ??

They seemed to have listed all popular songs to please everyone, but ended up pissing off every other. :rolleyes:
All these listed are surely great - no doubt about that, but not the greatest.
