I agree with all of your selections, sounds like I should have put more options on the poll. I almost kicked myself for not including "Voodoo Child" (Chile, whatever). That is the best song that he wrote in my opinion.
Did you ever heard him improvising? It's a total disaster!
I disagree, I think his solos are pretty sweet. They're just a little more influenced by blues and jazz than a lot of other soloist. Besides, at least he doesn't have totally scripted solos like a lot of other bands. As much as I love Oasis, most of their solos are written out and played the same way every time.
Jimi Hendrix was definitely one of the most influential musicians ever, not just in a musical sense, but he also sort of defined pop culture in the early 70's. He was definitely, in my opinion, one of the best and most innovative musicians of the 20th century.
Some of the other greats of 20th century music, in no particular order:
-Louis Armstrong, who made jazz true American music, and was also one of the first popular black musicians.
-George Gershwin, because he blended classical and jazz and brought it to the country.
-The Beatles. They pretty much redefined rock and popular music and, again, made it accessible to the whole world.
I know there's more, I just can't think of any right now.
