I think its fair to say i have a favourite genre, or multiple favourites, but that is no longer exclusive or exclusionary. All music is welcome, i will no longer judge a song by its genre.

I attribute the change to having different social groups in my life. When i was in school i was into rock and thwn metal and that was pretty much the only thing i liked. Later i got in with a crowd that was more into techno, dnb, dubstep, house, minimal etc and grew to appreciate it, around the same time i was playing in bands and learning the blues, and got into jazz more recently. Always liked classical because of my piano lessons when i was young. It opened my mind up to so much more.

Except pop :)
