After going the solo route for the first time in his career, Depeche Mode frontman Dave Gahan is now questioning his future with the band.

Gahan told Rolling Stone: "It's become increasingly difficult for me. When we go on tour and I'm performing, I know that I contribute a great deal to what we do -- in terms of bringing the songs to life on stage. But in the studio, it's like [keyboardist and songwriter] Martin [Gore] might as well be doing it himself... They're his songs, his ideas, and I'm the voice on top of it."

Gahan's debut solo effort "Paper Monsters," released in June, marked the first time he has written his own material.

"Unless he's open to both me and him coming into the studio with a bunch of songs and supporting each other, I don't see that there's any point in going on and making another Depeche Mode record."

Depeche Mode's last studio effort was 2001's "Exciter."
