A former Kmart employee uploaded the background music that was played in the shops in the 80s and 90s to the Internet Archive.

Until around 1992, the cassettes were rotated monthly. Then, they were replaced weekly. Finally sometime around 1993, satellite programming was introduced which eliminated the need for these tapes altogether.

Can you imagine working at Kmart for eight hours a day and you have to listen to the same 90-minute tape on repeat for a whole month?
