"Barracuda" is a rockin' little tune from Heart's 1977 LP Little Queen. The Republican Party has been using it as Sarah Palin's theme song of sorts. Heart is more than a little pissed about this.
Heart sent a cease and desist letter to McCain's camp, but they're still playing the song, claiming they've obtained all necessary licenses. Apparently you can get clearance to use a song like this without actually getting permission from the artists.
I don't believe the ad below is legit, but it's damn funny. I actually thought it might be real until I did some digging and found this. It might be fake, but Heart really is donating 100% of the royalties to Obama's campaign.
Crank it up.
