Meat Loaf and Bon Jovi doesn't work as a comparison -- one is to do with vocal 'limitations' and changes, and the other is down to musical direction. Jon Bon Jovi considers himself a business man, and he treats that band like a business. That's not a bad thing (from his POV). But if you grew up with a band in their original incarnation, stayed with them through the height of their fame (and back in the day that was pretty damn high), only to have them start pumping out a factory sealed 'lite' version of themselves, because, guess what, hair metal isn't selling anymore so let's try indie rock, damn, that didn't work, let's try the mellow acoustic approach, because everyone's doing that at the minute ... and on it goes.
Ah, the 'evolving artist' spiel -- untrue. I've followed enough bands since the 80s to be able to discern between the musical evolution of a band and a band changing their signature sound in an attempt to make their music sound relevant in order to push sales. And, yeah, that's what I'm saying Bon Jovi have done. I'm okay with it, I don't care about it -- but that's what happened, and what continues to happen. Bon Jovi have become a brand, a label, a franchise. It's a big business machine. Jon Bon Jovi has always had one foot in that world, but the other foot must've got amputated along the way somewhere.
Now I know that you're first instinct is going to be to come back with some big rebuttal, but honestly, I don't have the time right now to debate! You have your view, I have mine -- who cares, right?
You've been into the band for, what, five years? Think about that. Bon Jovi didn't just slowly evolve into another band -- it was an almost overnight switch. That's what happened, and what they do now doesn't appeal to me at all. But hey, if it turns you on -- go for it! And who knows ... I may end up even liking their new single (Stranger Things have happened).
