I was 14/15 in 1985, and I was just in the process of moving from being into pop music to being into melodic rock and NWOBHM. Bands like Def Leppard, Saxon and Diamond head were coming onto my radar, followed shortly by the US invasion of the '80s, with Bon Jovi, Skid Row and the like.
That's pretty much been me up until about 2010 or so, when I've started to listen to some rap and dance music, but basically If musicians made it, I'm more likely to listen to it.
