'That's Just the Way We Roll'
Never released as a single, this Jonas Brothers song was featured on their 2007 self-titled album -- which went platinum and peaked at No. 5 on the Billboard 200.
Kevin has noted that the inspiration for the video -- a period piece -- was 'The Notebook,' starring Ryan Gosling.
'When You Look Me in the Eyes'
A earlier version of the song featuring different lyrics and production appeared on Nick's self-titled 2004 solo album.
'Keep It Real'
Used on their television show 'JONAS,' this Jonas Brothers song refers to their onscreen mom's desire for them to be a "normal" family, despite the boys' fame.
A Jonas Brothers cover released in 2006, the smash hit was originally done by UK boy band Busted and became the 34th biggest seller of the year in 2003.
'Send It On'
This Jonas Brothers song was their second charting single (following 'Year 3000'), peaking at No. 53 on the Billboard Hot 100. The track was also included on the 2007 Disney Channel Original Movie 'Johnny Kapahala: Back on Board.'
'Play My Music'
The song appears on the soundtrack to 'Camp Rock,' the Jonas Brothers movie that helped put fellow Disney-approved rocker Demi Lovato on the map.
Nick told Elvis Costello the song came to him in a dream, and took only 10 minutes to write.
The inspiration for the song stems from the Jonas Brothers' "unlikely appreciation" for Prince (and his timeless sex symbol status among women), according to 'Entertainment Weekly.' The song debuted at No. 5 on the US Billboard Hot 100, making it their most successful single and our No. 1 Jonas Brothers song.
