I'm still mad about them not doing ALL of Passionate LOL.
Honestly the NKOTBSB tour was fun but not something I ever want back. That said, even though I love having Kevin back I do think Nick grew a lot as an artist during that time so, in a way it's good those albums happened without him. Not to mention some real gems came about then like Downpour, Undone, This Is Us (the song), Unmistakable, Everything But Mine...not to mention unreleased songs like On Without You and Trouble. I also wonder if the Boys would've broken down that wall between the fans without Kevin there. Like that's when VIPs started, that's when the cruises came. Who knows?
But NKOTBSB brought back 10,000 Promises and If You Stay and had Nick singing Raspberry Beret so, it had it's good moments too.
I agree though that rearranging the classics can really backfire. Sometimes it's good - like I enjoy when Nick does that sort of thing with his solo songs. But other times no. As for set lists, I'm over them ignoring Unmistakable and In A World Like This, and This Is Us with the exception of Undone. We like those songs too!
The DNA tour did a good job trying to include some deep cuts. I live for It's Gotta Be You coming back and I Wanna Be With You.
