The title of the album, "A Little Bit Longer", comes from their song of the same name, which Nick Jonas wrote about his feelings with having type 1 diabetes.

The brothers performed their second single, "Lovebug" at the 2008 MTV Video Music Awards One of the extra tracks, "Live to Party", was later the theme song for their television show Jonas.

[4] On October 17, 2008, the album was certified platinum by the Recording Industry Association of America (RIAA) for sales of over a million copies in the United States.

In a 4-star review written by Rolling Stone editor Jody Rosen he stated, "The boys fantastic third album is steeped in the fuzzed-up guitars, three-part harmonies and cotton-candy choruses of Big Star and Cheap Trick.

Jersey-born Jonas siblings Nick (15), Kevin (20), and Joe (18) hit all the right pop notes with such numbers as the romping come-on 'Got Me Going Crazy', the slightly funky 'Burnin' Up' (a very pale imitation of Prince) and the emo-lite of brokenhearted ballad 'Can't Have You'".

In a mixed review from the Toronto Star, Ben Rayner when speaking about the albums demographic wrote, "Young hearts will melt, elder stomachs will churn", and "[A Little Bit Longer] has one uncritical audience in particular in mind and it serves it as well as can be expected".
