Since oil change places were mentioned, the garage where I go has oldies playing. I used to hear radio stations that played alternative rock, classic rock or mainstream rock. But now it's consistently the one radio station. Which makes sense since the garage is an advertiser.In smaller workspaces, I'm sure that's how it's done. In the Salvadoran Restaurant they had a Pandora channel playing Salvadoran music. When people are working, they're not paying close attention to the music, after all. A lot of it is just background noise / music for the workers and/or patrons.
