Well I am a Jovi fan today because of the stuff they did in the 90s. These days, Keep the faith and even Jon and Richie solo projects.

It's not that the 90s stuff wasn't commercial, it was. But despite that the songs were so much more interesting and intricate. The drumming, the bass lines, the guitars, vocals, everything...

I think that now that they are older they probably don't have the motivation to spend as much time on the song writing process trying to create something interesting. Earlier music was their life, now they are family men.
