That makes perfect sense to me. I have plenty of contemporaries who seem to be very happy sticking with the music that they (and I) grew up with - which is all very good stuff. But I think I always had a dread of being left behind in the past in terms of my pop-culture interests - it just seemed to me to be very sad, and not what I wanted to do.
I'm staying away from Western pop culture now largely for personal/psycological (i.e., utterly irrational even to me) reasons, but if I weren't, I would be continually on the lookout for new stuff - as it is, when I do go to an event and hear a new / recent local (SGV and by extension, the entire L.A. area) band, I frequently like what I hear, which makes me happy. And within the context of Asian pop music, I'm continually on the lookout for new (and old, but new to me) performers to listen to obsessively - it's really the only way that I could do it.
Maybe the bottom line is that personal taste by its nature has to be personal, and that the best thing to do is simply to trust your own taste, whether it makes sense to anyone else (or even to you).
