yeah i hear that, the late 80's to late 91 you had guns and roses and aerosmith and hair bands as far as rock, there was some descent alternative at the time. Plus REM, U2, Tom Petty and some others never really faltered.
looking back i do like it, even the hair bands
its just have good time and party music
The same thing happened in the the early 60's after buddy holly died and until the beatles came, all you had was the beach boys for 4 years.
I remember exactly where i was the first time i saw the vid for teen spirit, I said this is it, these guys will be big.
Side note: for some reason 80's rock is big in south america.
All the little rockeros like guns and roses and the hair bands, but 70's and 90's rock is pretty much never heard, never played..... I guess its just to profound for them to grasp.
