KEVIN: We co-wrote several tracks with Max Martin. Brian and I each wrote two tracks on the album. I wrote a song called "Back to Your Heart" with Grammy Award-winning songwriters Gary Baker and Jason Blume. I went to Alabama and spent a week at Gary's home and I got on the piano and started playing a song that I'd been working on. I started singing it a little bit, he picked up his guitar and about two hours later we had "Back to Your Heart."

BRIAN: I wrote "The Perfect Fan" about my mom because she's always been the perfect fan. I think everybody has a mother figure to whom they look up or someone who has been there to guide and help them through life. I wrote the song about a year and a half a ago. We were on tour in Spain and when I finished the production, I went home to Kentucky and I had my high school choir sing on the record. So it was kind of allowing them to enjoy some of the success that I've had. It was cool to give back. I wanted to thank them.

AJ: "Don't Want You Back" is probably my favorite song because it is a complete opposite of what you've heard on the previous Backstreet Boys albums--talking about love and relationships. It's talking about not wanting to be with someone--I just don't want you back, you're out of my life, goodbye, see ya. And when we perform it live, the choreography is phat and the whole vibe onstage is really cool.

NICK: I think "Don't Want You Back" is a very good song as well as "Larger Than Life" because I love rock music and that's the closest thing we've come to doing rock. I also like the song "Spanish Eyes" because it's a really unique sound.

NICK: I think our main priority is definitely to hit a lot of countries on this world tour where we haven't been yet. Places like Russia, South Africa, Iceland, the Middle East. We realize that there are a lot of Backstreet fans around the world--we want to make sure we get totally in touch with them.

AJ: Oh, yeah we definitely remember Chile. We were kinda stuck in our hotel room, for however many days we were there--like almost a week. We were practically under house arrest! We couldn't leave the hotel, but Chile was incredible for us.

NICK: It's gonna be about a two-hour show with about 18 songs. We are doing it in the round, so that was another difficult challenge for us to try to take on. We wanted to step up to another level because our last tour was pretty successful. But we also wanted to set trends and just be on that next level, so hopefully that's what this tour will do for us.
