No need to wait until 6:00 pm ET, folks -- U2's "Invisible" is now appearing in some (if not all) iTunes stores around the world. You may not find it by searching for "U2 Invisible" and things like that, so try this direct link.
The song's official title is "Invisible (RED) Edit Version" and it runs 3:47. ITunes is showing the image attached as the single cover.
What's your reaction? Feel free to join the discussion in our forum.
UPDATE: U2 has posted a three-minute video offering some behind the scenes-style footage and commentary about the evolution of "Invisible," which Bono says originally was written about being in a train station. You can see that on U2's Facebook page at the moment.
You can also see the actual Super Bowl commercial that will air today, which we've embedded below.
