I'm 17 and the only Journey stuff I can't listen to is the Pre-Perry material and the bulk of the Augeri era, save for Higher Place, All the Way, The Place in Your Heart and Remember Me. And I made sure to YouTube the non-Augeri Generations tracks, which are a bit disgusting, save for In Self-Defense, I kinda dig Neal's voice on that and People and Places.
ROR, despite all the bullshit, has some cool stuff. Positive Touch was good for the verses, but I'm only just warming up to the sax solo. It Could Have Been You, WCTNGOF, Be Good, I'll Be Alright, Eyes of a Woman and Girl Can't Help It are all some of my favourite Journey songs. I'm singing BGTY in my school's rock band. Pretty intimidating stuff. I seem to be ok at some of the 78-81 stuff, and the Frontiers and Street Talk stuff as well... I guess I haven't deteriorated enough for ROR tracks

Oddly enough, some of the FTLOSM and TBF things come easy to me.
