Announcing the Lineup for the 2015 iHeartRadio Music Festival!

There are several things we can expect in September each year: the beginning of fall, pumpkin flavored drinks, and most importantly, the iHeartRadio Music Festival! Okay, maybe we’re a little biased…still, there’s no denying that the highly anticipated mega-concert rewrites radio history each year and gives us a reason to break out our shorts and sunglasses just one more time.
