Both decades had great music (and plenty of shitty music too).
I guess i kinda came of age in the 90s, so it's always felt like a special time in music for me personally.
A lot of the 80s music i like is stuff i discovered long after the 80s were over, whereas a lot of my favourite 90s stuff will be forever linked in my memory to the time i first heard or discovered it, or when i saw the band live (like the song i posted above).
For my money though, there has never been an era in popular music that has come close to the 1960s.
I kinda think of the 90s as the last innovative musical decade.
Maybe i'm getting old, but a lot of music and music culture since the turn of the century has been rehashed from earlier things.
Still some great music, but the second half of the 20th century was a pretty amazing time in music, and a lot of that had to do with technology.
The information age has had a weird impact on art.
