spotify on another service

[mae9000]

I'm a design student, I just wanted to ask if it would be okay to use music from spotify for another business? it is not a real company, but if it were, how would the process be like, legally speaking? it's a hypothetical product which connects to spotify and plays music from it. it's a student project for design which uses music from spotify to help cooking for people with executive function disorder.

It is used in a private settings, in home kitchens, and not in commercial spaces, so it just uses the music from spotify on another device, i.e. speaker.
