Alternative, New Wave, are VERY broad terms. .
One has to suspend logic to enjoy Lithium; here are some of their regular artists:
Goo Goo Dolls,
Toad the Wet Sprocket,
Dave Matthews Band.
I don't consider any of these to be 90's alternative. However, if they really stuck to the formula, they'd overplay the grunge that much more. So it's a no-win, in my opinion.
What are Goo Goo Dolls, Wallflowers, Matchbox 20, and Creed "alternatives" to? If I'm correct, the term "alternative" is used to distinguish artists from the mainstream of pop music. None of these bands were played on the alternative stations I listened to in the '90's.
Admittedly, the other bands I mentioned (Dave Matthews, Gin Blossoms, Counting Crows etc) did get airplay on alt stations back in the day. But looking back now, they're about as mainstream as it gets.
Alternative, New Wave, are VERY broad terms. Just because something was a hit, or even from a major artist does not make it less of a fit per se.
When I lived in Hampton, VA, I used to listen to 96X (Year of the X = 1996 )
All the bands mentioned were played along with bands I never heard of before, or since.
Big Head Todd and the Monsters
Just to name a few
Plus they played the regulars like...
Dave Matthews Band
It was a very good station. I wish Lithium was more like old 96X
