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?...
