Interesting. I'm not really sure where I fall in this discussion, though I must admit to being "stuck in the past" to a large degree.
I've been listening to music constantly since the mid 70's, really got passionate about it in the 80's. By the time the mid-90's rolled around I was REALLY burnt out on anything pop/rock, so the intense study of jazz began. After spending almost a decade listening to mostly jazz I realized I was getting tired of that as my only musical diet...so I started to both check out newer bands in the pop/rock world and also revisit some of my favorites that I had neglected for a very long time.
Now? Most of the newer music I listen to is very much inspired by the stuff I was listening to in the 70's and 80's, so much so that many of the artists could fool someone into thinking they are listening to a "lost band". Why? Because the musical vocabulary from that era still resonates with me very deeply, I don't want to hear samplers...I want to hear mellotrons and Hammond organs and vintage tube guitar amplifiers. It's the most "real" to me. Thus I tend to gravitate toward musicians that feel the same way as I do.
I've also found that the music I listened to as a "pre-teen" sounds more fresh to me now than the stuff I was playing around my teenage years. Probably because I neglected that music the longest.
