Bon jovi is not pop music! Living on a prayer has no hard riffs, no big solo and so on. so what makes that song a rock song? I don't know, but it's not all that diffrent from for exampel Bounce or Everyday. the lyrics are better but thats just the only thing I can come up with that makes this song a rock song, if that makes a song a rock song, wich I don’t belive, many pop artist has done some great songs with great lyrics for example Earth song (michel jackson), i'm not sure thats the name of the song!
