Alright the 90s brought some great music in my opinion, mostly Grunge rock, but what is everyones personal opinions on the best of the 90s?

My Personal Favorites are:
Nirvana
The Smashing Pumpkins
Alice in Chains
Tool
Foo Fighters

I agree. I grew up in the 90's listening to country (which I still love) but I love 90's alternative. It makes me happy

90s to present is my favourite time in music. I'm assuming by the examples you gave that we can include bands that are active today, as long as they started in the 90s, or at least released their first album or whatever?

Of course there's Nirvana.
Mr. Bungle (one of the most experimental bands ever) released 3 albums.
Amen started in '94.
Refused, who released one of the best albums ever.
Eminem got big in '99.
Slipknot got big in, I think, 99 as well.

And look at that, a lot of my favourite bands/artists started in the 90s.

the 90's is my favorite time period too! almost all the hip hop i listen to regularly is from the 90's

Yeah, a lot of good shit originated in the 90s. I'm sure a lot of the hip hop I listen to started in the 90s too, but I didn't give it a lot of thought.
