Has anyone else noticed that bon Jovi seem to have followed a certain pattern with their single releases from their last 3 albums? (Crush, Bounce, HAND)

I'm meaning first single has been quite an upbeat rock song, second single has been mid-tempo(if that's the best way to describe it) and the third single a ballad.

Crush:

It's My Life : Upbeat
Say it isn't so : Mid-tempo
Thank You For Loving Me : Ballad

Bounce:

Everyday : Rock
Misunderstood : mid-tempo
All about Lovin' You : Ballad

HAND:

Have a Nice Day : Rock
Who Says You Can't Go Home : Mid-tempo
Welcome to wherever you are : ballad

Maybe i'm talkin crap but I noticed it a while back, just thought i'd see what everyone elses opinions were!
