I remember that the Nintendo Entertainment System cost $215 when it hit the market in 1985. I didn't get one until two years later; it came with Super Mario Bros, while my mom also got me Kung Fu and The Legend of Zelda.
I remember being in awe of Tone Loc's "Wild Thing," mainly because I'd never really heard such a dirty song before, especially on the radio. Around this time, I acquired Prince's Purple Rain on cassette, though the masturbation reference in "Darling Nikki" went over my prepubescent head. That Prince tape, by the way, was the only "cool" musical item in small cassette collection. I also had Europe's The Final Countdown and the David Lee Roth solo album, Skyscraper.
And Wham!'s Make it Big. "Wake Me Up Before You Go Go" was the jam back in the day.
