I've spent hours listening to this kind of ambience while working, but for me it's a little too bland. Video game music on the other hand is perfect for working. I've had this one on repeat for the past 10 days.
You should like the JSR site then! The creators have put a lot of love into their site.
They have multiple music stations, multiple “TV” channels, a graffiti board, and a chat box that all try to recreate that Jet Set vibe. Just be cautious opening that graffiti board at work...
Same for me. I've found maybe a dozen or so creators who put together large (2-10 hour) playlists of game music, mostly from older RPGs (or even better, custom remixes.) Some also have mixed in ambient thunderstorm/rainstorm effects
They've been fantastic for helping me both stay relaxed and focus in on whatever I happen to be doing
