Lofi music is a really popular genre to listen to as background music, I wouldn't say it's a tired genre. Perhaps for creators it is, but for listeners it's not.
How much background music do you realistically need though? If there's a few thousand hours, would you notice if it repeated at some point?
(Assuming the general style of the genre is staying similar and you don't listen to specific songs you discovered but just put on some collection of songs from the genre.)
Is there new elevator music being composed all the time too?
The rebellious authentic music from the current middle-aged or old people's youth is todays elevator music. I've heard the Pink Floyd's the Wall being played at a soothing volume in the grocery store as I tried to find lactose free milk for my adult children's visit.
Atleast for me the repetition is the point. It's calm enough when I'm working but I get a little jolt of joy whenbi recognise a groove I really liked before
