Are you talking about the fedora/martini era stuff or the later material? I've had thoughts of decorating a basement music room (when I build it) with some nice late 50's americana. Something with a rat pack/Ray Charles/Nat King Cole motif.
Later. The late 1950's and early 1960's, when the term "Space Age" was popular and Tang was The Astronaut's Drink. Bachelor Pad music, also known as Elevator Music, Space Age Pop, or whatever, it was early 'environmental' music that tended to be heavy on keyboards, early synthesizers, and made heavy use of multi-track recording techniques. I believe it to be a child of Jazz in a sense - many or most of the most prominent electronica musicians came from that background.
Think about the TV shows of the early 1960's - most had this type of music as a theme song - Hawaii Five-0 being the most memorable.
This is a good example of what I mean.

From that, I find that I also kind of like the idea of listening to this kind of music on vintage equipment - the sort that would have been used in a swinging bachelor pad, don'tcha know.
And from there - well, why not decorate the room from the same era? Eames, mid-century modern, Heywood Wakefield, whatever you want to call it. It did get started during the Rat Pack days, but it overlapped the later Space Age days as well.

I just dig it all. Mrs. Wiggy rather hates it, music, equipment, and furniture, but me, I want a clock like this on the wall:
And maybe a macrame wall hanging and a tiki torch (unlit, of course) and a wet bar with a Hamm's Beer sign on the wall in neon.
If I still smoked, I'd use a cigarette holder or smoke a pipe while wearing a sweater with elbow patches.
Woo doggies.
