Cripes, I remember all of those extremely well. Especial "Open Arms" because my girlfriend at the time absolutely loved that song. And since I had it, thanks to it being included on the soundtrack of the movie Heavy Metal, she insisted on hearing it. And as luck would have it another girlfriend, over a decade later, also adored that track. I also remember hearing "Another One Bites The Dust" countless times in various roller rinks. But yeah, if I had a dollar for every time I heard all of the above on the radio back in the day I'd be filthy rich.
I think I might even have the track "Beth" on a 45 still.
