I loved WCGY's midnight album plays. They spun some really obscure stuff, and it was on vinyl too, even in the CD age.
Loved the retro sound of the Eagle too.
Mike, Jack, etc, etc are fine for variety, but the novelty wears off. What's missing are the personalities presenting the music. And yes, the 00s are bad for music, but the problem for Jack and Jill and Jim is that the 80s and 90s aren't great either. They don't have the staying power of the 60s and 70s. Come On Eileen and Safety Dance, for example, are great as novelty songs, but they ain't the Beatles or Supremes.
I think what happens next is anyone's guess, but one thing for sure: people under 25 hardly listen to any radio at all.
