That actually sounds a lot like a store we used to have out here called Gemco. In fact, the one I had near me was actually replaced by a Target in that same location after Gemco went under. I don't think anybody had yet heard of Target, so that was interesting. And, yeah, Gemco had music too. I remember seeing Y&T cassettes there, but can't remember if I actually bought any. I got most or all of them from The Wherehouse.
