I certainly won't quarrel with your tastes in music, especially since I too like a lot of classic rock. I do have a quibble with your taxonomy though: Bon Jovi, along with bands such as Whitesnake, Guns and Roses, Motley Cru, and Van Halen aren't really classic rock; they are part of a genre called hair metal.
Classic rock is normally considered to be that rock and roll heavily influenced by the so-called British invasion from the Beatles through the end of the seventies, though some music that would fit within that genre is still being created today.
A lot of people didn't like the commercial/poppish sound of eighties music. Alternative, or Indie, got its name as a less commercialized alternative to hair metal.
Happy listening.
