I've always connected with a great deal of the music from my parents (or grandparents) generation. Jazz, mostly. It's what my mother listened to when I was a kid so it left a good impression.
Nothing wrong with liking music from many eras. It seems to be what separates the casual music lover from the hard core. The hard core always seem to know music from way back to now.
I guess there are times when we end up liking a certain kind of music because of how it has been introduced to us. It becomes more meaningful since the music is transformed into something that's beyond the notes and melodies such as memories.
