Eight Minutes. That's all it took the 2012 edition of the iHeartRadio Music Festival to sell out. The Las Vegas event, which is scheduled for Sept. 21 and 22 and boasts big acts like Taylor Swift and Miranda Lambert as featured attractions, is one hot ticket, needless to say.

Country's Brad Paisley and Jason Aldean are also on the bill, as are acts like Aerosmith, Rihanna and Lil Wayne, to name a few. It's a healthy and diverse mix of the biggest names in music -- all genres. The festival is slated to take place at the MGM Grand.

If attending the event isn't possible for you -- due to the fact that you don't live in or near Vegas or didn't get in within the 8-minute opening -- there is still hope! A live video broadcast will take place via Yahoo!, the official and exclusive web and mobile partner for the event.

The 2012 iHeartRadio Music Festival will also broadcast on Clear Channel station sites. So all you Swift/Lambert/Paisley/Aldean fans can tune in in September and take in all that they have to offer at this major sold-out radio event.
