I agree w/Vasco Rossi and Ligabue, but there's large slot of BJ like genre here and one could enlist many artists including females: Irene Grandi, Laura Pausini, even Francesco Renga, Litfiba, Nek or Massimo Cataldo or ...Negrita. I'm talking about ALL BJ songs, not their hits where they display more originality.
Their ballads are very Italian like & I was intentionally mentioning Jon's roots to show that some of it might have come from his Italian soul, be it only 25% LOL

I do believe that's actually Bon Jovi copying music style of certain bands (rather american ones: Tom Petty, Springsteen, Aerosmith just to name a few)....they fell out of hard rock genre long time ago, right after TD, especially Jon with his Destination Anywhere...
since Crush they pop rock, and that's what Italians do so well! So they melt in here : the only difference is .. the language barrier, that's where they sound different LOL.

to play really good hard rock you have to be somehow verrry angry w/sth or someone, and BJ were only to the certain limit & so Italians do, they are very relaxed and romantic nation, and so is the BJ music in general.
but since BJ are really able to evolve withing each record (as for instance contrary to U2) they are always surprising me with new solutions and uncomparable sounds that do not echo any other other band or artist on Earth ) & that's probly why I did listen to them faithfully for past 20 years, still do like to listen to them great deal each day, anxiously waiting for each new album LOL

see ya
