Glynsky uses the word cool a lot. He even created a category for it, I don’t really know why. In the early days of diablog, Glynsky first mis-attributed the title “King of Cool” to Tony Curtis. Only after a while he admitted that my correction – Steve McQueen, obviously – was correct.
Anyway, there is one song, that could very well be called the coolest song ever. It is minimalistic, yet makes you move your feet. It is extremely memorable, you are not likely to forget it, after hearing it once. And it just oozes cool.
Green Onions by Booker T and the M.G.s., added bonus: the vinyl scratching.
It is among the Top 500 of all time, part of numerous movie soundtracks like Quadrophenia and Get Shorty, and is one of my all time favorites.
