I liked some big band stuff as a kid of the 80s. I think due to Xanadu.
My 10.5 yr old nephew has loved elevator music since he was at least 6, although mostly likes whatever the youtube biggies write for video games, like the Fnaf series (The Living Tombstone is a favorite of his now).
I didn’t introduce him to elevator music either – he found something on youtube and liked it and occasionally will share something with me that’s elevator-y.
Anyway, is it a dead genre forever? I don’t think so. The wah-wah trumpet is DEFINITELY not dead… and this works GREAT as a comedy bit.
As far as sentimental goes? All you have to do is enjoy the Wizard of Oz as a kid and you’ll have a sentimental spot for cheesy violin sentimental music for a lifetime.
