I still hope that one day everyone will be into GN'R again.
It would be cool to see people wear GN'R stuff again and being talk all over the place.
It'll never happen. There is too much choice out there now with all the different types of music and the different means with which to hear it. Satellite radio, internet radio...its too easy to listen to new stuff and find your own niche. Popular music seems to change every 2-3 years too in every genre of music. Since the death of rock/hair rock, in the 90s alone, you had so many different types of rock:
grunge (pj, stp, nirvana)
nu-metal (korn, linkin park)
rap-rock (limp bizkit)
ska rock
then what I call puss rock - but I guess thats always been around (match box 20, goo goo dolls, etc...)
I honestly wouldn't even know what to call todays rock.....I guess its somewhat emo rock now? Well, I guess you could call it what I call it...Total SHIT!
I don't think you'll ever see a type of rock music, new or old dominate the charts for more then a year or two the way we have since the 80s.
