OK Go's just released a 3-song single called Do What You Want. T'other two songs are "Invincible" and a cover of "The Lovecats" by The Cure. It's sooooo not bad.
Buy it at the iTunes Store, Amazon.com, and a host of other places. You can also listen to two of the songs, for free, at okgo.net and myspace.com/okgo page.
