What to do with the cassette tape in Stray
Once you have the cassette tape, you must find the cassette player. This is located in the clothes shop in the center of Midtown. Head into the fashion store and go to the back room. There you can find the cassette player in the corner of the room. Walk up to it and interact with it to insert the cassette tape.
This will cause the cassette player to turn on and start playing loud music. The clothes shop owner will head to the back and try to turn it off. Use this moment to grab the Neco Factory work jacket off the mannequin. This is an important story item that you must give to Blazer to sneak into the factory and steal the Atomic Battery.
