I worked at a used record store many moons ago. I got familiar with jazz, Hawaiian and goth music as well as classic rock and radio pop.
The first time I heard Mariah Carey was when our store got a shipment of cassette singles. Yes, one song pressed into a "cassingle". The "B"-side might have been the instrumental though I can't remember.
I played Mariah's first single, "Vision of Love", until my co-workers would groan disapproval and hide the tape from me! Hahaha! I said she was going to huge so get used to it...but really, who knew I'd be typing into a computer all these years later?
I did make the effort to see her first TV appearance!:
