And it sounds like typical Bon Jovi ballad, only with the popier feel of that time around 2000. I also fits the mood the were in lyrically. They didn't write about the same as in I'll Be There For You but rather from a long term relationship prespective. It corresponds with Just Older - they felt kinda old
All About Lovin' You sounds more like someone else's songs, at least musically and in arrangement. The chorus sounds like Bon Jovi.
I think they didn't play TYFLM that much because the already had many big ballads to play. Mainly Bed Of Roses, then I'll Be There For You, in 2001 Always returned. They skipped TD ballads completely (somehow These Days the song is not a ballad in my book).
