The Jonas Brothers are seriously taking the saying "quality, not quantity" to heart, waiting four years to put out new music after 2009's 'Lines, Vines and Trying Times.'

The guys have yet to announce an official single or release date for their 2013 LP, but Kevin, Joe and Nick Jonas did say they are taking songwriting inspiration from pop heavy-hitters like Frank Ocean and Adele.

The JoBros' upcoming album is already shaping up to be more lyrically personal, as evidenced by the trio's moody new track about Miley Cyrus, 'Wedding Bells,' which they premiered live in 2012. Their other two new tracks, 'Let's Go' and 'First Time,' reveal a more mature sound that leaves their Disney days where they belong -- in the past.
