The cool factor- who has it?


My question relates to music and musical artist's performance and music. Who has that COOL factor?  In the past or currently. For example I think the Beatles had it and also Bob Marley. Today I think Lenny Kravitz (if for nothing certainly for his longevity).

Thoughts?...

@jnovak - I always liked that 'great folk scare' - did you ever see the movie 'A Mighty Wind', which was made by the same people who did Spinal Tap, but instead of metal, it deals with the folk music scene and their band is called the Folksmen. Those guys are/were cool.... 

Noticing the frequency of the usage of "cool" nowadays, it is apparent that darn near anything can be called "cool." In second place - "awesome."

Jim Morrison and the Doors, Bonnie Raitt,Greg Allman,David Bowie, Dave Mason,Roger McGuinn,Cher, Dean Martin, Tony Bennett,  Aretha Franklin, Ray Charles,Tom Jones....Rock and Pop...

Lester Young was "cool"  and one of those who use this adjective...Chet Baker was  refered as "the Prince of cool" by contrast  but at this time this was a jazz adjective linked to black musicians.
