In case you haven’t heard, MySpace is back — or at least they’re attempting to come back with a sleek, newly designed website that’s loaded with music-oriented content and interactive features that just may be cool enough to lure users back in. Tapping musician Justin Timberlake (who you may recall became an investor in the struggling social network last fall) to help promote the site’s re-launch, the company has just debuted a new promo video that gives us a peek at the new and improved MySpace. We’ve dissected the video frame by frame to help you decide whether or not the service is worth signing up for. — Adrian Brinkley
