The Jonas Brothers are finally delivering their comeback, leading JoBros fans to ask one question: C'Mon guys, what took so long?!

Turns out, there's a pretty reasonable answer to that.

The guys are perfectionists who've grown up a lot, and they wanted to record to accurately and fairly reflect it. "It wasn't right where we wanted it to be," Kevin Jonas revealed to MTV News. "It wasn't progressive enough. I think this record we wanted to take the time needed."

Nick explained that their individual side projects also played a role in the delay -- not just in terms of scheduling, but also in terms of musical direction on the album. "I think it was a collective decision. We came to a place where we had sort of done our individual projects, and it felt like we were in a place where we were ready to create again and come back with some different inspirations," Nick dished. "And we knew it was important to make this different from our previous releases and step outside of our comfort zone and really make this our best record yet. We worked hard and we took our time with it too. And we're very proud of the result and excited for fans to hear the rest of the record besides 'Pom Poms.'"

As for their warm welcome back to the pop scene? "It feels really nice," Joe smiled. "It's kind of like we never left. We spend a lot of time together, even when we're not doing music, but finally making music together is great and we are very happy that people are actually showing up to concerts and listening to the music yet again."
