O.A.R. wants to write a song with you. Via Twitter.

The jammy, island, pop-rocky sorta whatever band is encouraging fans to cobble together lyrics utilizing Twitter's 140 character limit.

O.A.R, or Of A Revolution, will pick a chorus, a bridge and verses after sifting through the entries, with submissions allowed beginning now through July 7. Winners will be picked July 21.

Entrants can submit more than one Tweet for consideration, but only one entry per entrant can be selected. Lyrics can be sent to twitter.com/ofarevolution or simply by Tweeting to @ofarevolution. If you don't know what tweeting is, just forget about it.

The music for the single will be written by the band and will go up for sale on iTunes in October - but not before the band can run another Twitter contest to name the song from July 21-28. Proceeds will be donated to the Heard the World Fund.

According to the website, "Each winner will receive two tickets to the O.A.R. concert of their choice in 2009 or 2010 and will be able to meet the band (subject to availability)."
