Yep exactly. In the big chain supermarket near me they continually play their brand jingle, along with ads for themselves. The jingle is repetitive and simple, just 7 notes that match the syllables of the "lyrics" - a tedious line about fresh food.
I'm already there buying stuff, so can only guess their tactic of spamming the store with their jingle, is based on some theory of reinforcement.
I've also noticed a news radio program I sometimes listen to, is now taking more breaks to advertise themselves. Not programs or content, but just how good they think they are in general, and how trustworthy they are. It's self-congratulatory cringe. The person who decides if they're trustworthy is me, the listener, not them telling me over and over that I should trust them.
