Ofc anyone can write a piece of text like this, including on this board. So different views are always expected. Let's not take things here so seriously.
For ME a Jovi ballad:
has powerful vocals
is emotional
has a guitar solo
is on the "slow" side of the album
is a classic
Not necessarily all 5 in the same song, especially #4 and #5. So for me, songs like Always, IBTFY, NSG, TAAS, BOR, Living In Sin, Only Lonely, Silent Night, Lie To Me, Make a Memory.
Maybe Wild Is the Wind and ITA.
But not Letting You Go, Diamond Ring, Say It Isn't So, Thank You for Loving Me, She's a Mystery, Superman Tonight, and some other examples.
Again, this is just me. When someone mentions "Bon Jovi ballads", those are some of the songs that come to mind.
