Every generation has it's own music that it grew up with. Bad or good, it brings back memories of being in high school or your first love, etc. The older you get the more you miss what music means to you. When you hear an old fav on the radio, you zone back to your youth. New music will not do that for us older(ugh, I hate that word) ones. We may like new music, buy it, download it, dance to it but it will not remind us of when we were young. You youngsters will figure that out when someone starts to make fun of the music of the 90s and 00s.
I split my time between my old favs and listening to new music. There is a lot of good stuff out there. The trouble now is you have to look for it. You won't find it on the radio. But no matter how good it is, it will not have the effect that the music I grew up with has.
