Should stuff you have nostalgic attachment to really count?
I mean, a lot of music from the 90's that I still listen to doesn't really align with my current tastes but I grew up w/ it so it's impossible for me to be objective. Mentioned this recently when we were discussing The Offspring, who definitely qualify (or at least "Smash" does). Other examples: Marilyn Manson, RHCP, White Zombie, Green Day, Sublime, Live, Coolio, Warren G, Manu Chao- I own and enjoy at least 1 full album by each of those artists. And if we were talking about just enjoying individual songs, there'd be countless more examples (from all eras, actually). And though I generally don't want anything to do with modern mainstream hip hop (though I guess you could add "Pimp A Butterfly" and "Untitled Unmastered") or R&B, I love a lot of the stuff from the 90's (partly because I do think it's objectively better but I'll admit that nostalgia is definitely a big part of it).
If we're talking non-nostalgic stuff, Dog Faced Hermans are a good recent example. Others: Alice In Chains and The Jesus Lizard (both 90's groups but only got into them recently), The Raincoats. Anything that smacks too much of either punk or metal is typically not my taste so any artists who fall under those umbrellas probably qualify. And though I do like country and bluegrass, I don't listen to very much of it so you could maybe add Doc Watson, Townes Van Zandt, Roger Miller, The Holy Modal Rounders, Lee Hazlewood, Johnny Cash, Patsy Cline and R. Crumb & His Cheap Suit Serenaders as well.
