You can't rock the vote any better than this....

Confirming a couple weeks of speculations, a mega lineup of artists including Pearl Jam, Dave Matthews Band, REM, Bruce Springsteen and Dixie Chicks, have announced the not so subtly-titled Vote For Change Tour. The bands will play shows during the first week of October in a number of swing states (areas where the popular vote between the Democrats and Republicans is expected to be close). For the politically challenged, we should explain that U.S. presidents are determined by how many states they win the majority of votes in. Each state is worth a different number of points based on its population, so populated states like Pennsylvania, Ohio, Michigan and Florida are key battlegrounds.

Springsteen will be on Nightline tonight talking about it. Here's the lineup, divided into six groups:

• Pearl Jam with Death Cab For Cutie
• Bruce Springsteen and the E Street Band with R.E.M., John Fogerty and Bright Eyes
• Dave Matthews Band with Jurassic 5 and My Morning Jacket
• Dixie Chicks with James Taylor
• Jackson Browne with Bonnie Raitt and Keb' Mo'
• John Mellencamp with Kenny "Babyface" Edmonds

Each group will play in a different Pennsylvania town on October 1. The tours will move on, with some or all of the bills hitting cities in Iowa, Michigan, Ohio, Wisconsin, Missouri, Minnesota, North Carolina and Florida.

Any chance the concerts could be made available on pay-per-view around the country? It could be a great source of revenue for the party and the candidates.
