ET has the details on the Jonas Brothers' new album, which includes a Nick Jonas-penned tune about a "confrontational relationship"!

The JoBros' highly anticipated fourth CD, Lines, Vines and Trying Times, will be unleashed worldwide June 16, with the album's first single, "Paranoid," arriving on radio and online May 8. The single will become available for digital download on iTunes starting May 12.

The album finds the brotherly trio boldly stretching their musical boundaries -- several of the songs incorporate horns as well as harmonicas and peddle steel guitars. "Paranoid," however, is a guitar-driven dance ditty in the mold of Jonas Brothers gems past.

Another notable tune is "World War III," a "funk metaphor for a confrontational relationship" written by Nick, who calls the song "a personal experience for me" that "deals with the challenge of a girl who keeps attacking you, provoking you, trying to fight you, but all the while she's the only one fighting."

Lines, Vines and Trying Times is the follow up to the No. 1 debut of A Little Bit Longer and the No. 5 debut of Jonas Brothers.
