The cool factor- who has it?

Why is it my job to bring up the Queen of Cool?

Paul Weller, Joe Jackson, Marvin Gaye, Curtis Mayfield, Sly Stone, Amy Winehouse, Steve Marriott, John Waite, Free, Chris Robinson, Jason Isbell, Elvis Costello (in a nerdy kinda way) Dolores O'Rierdon, Kay Hanley, Sting... just tossing some out there that haven't been already named. So many among us now, but so many gone too soon

Kool and the Gang

I did cool to their early days before they declined and melted away and became lukewarm. Their second peak was in the 80s and for me they went from lukewarm back into cool again.

I am not a fan of Blues but there are exceptions... I admire John Lee Hooker voice singing so cool anybody feel in a hurry compared to him...

I always like to hear him since 50 years and i love him so much it kill many others Blues singers for me ...

I like Moody Blues but he was way less cool than Hooker...

The Beatles, Pink Floyd, Steely Dan are the first to come to mind.
