You can create associations between music and states of mind. As you said, Monday looks completely different from a Friday, so adjusting the type of music (tempo, instrumental/vocal, genre, etc.) to the time of day can predispose people to a certain mental state. And the body will react as well.

You might be creating a Pavlovian association, by pairing music with certain settings, and whenever they hear that music again, they will immediately be transported to that context.

It's like getting people in their zones through sound ;)
