The lineup for the 2014 iHeartRadio Music Festival was posted today, confirming that it will be just as star-studded as past years. Taylor Swift, Coldplay and Usher are among the top acts for this year.

Other acts scheduled to perform are Ariana Grande, Nicki Minaj, Motley Crue, One Direction, Ed Sheeran, Paramore, Iggy Azalea, Train, Calvin Harris, Bastille and Steve Aoki.

A new group named Before You Exit will perform as Macy’s iHeartRadio Rising Star act.

As Billboard notes, the festival will be well-timed for Swift, Usher, Minaj and Harris, since they are all releasing new music this fall. The performances will give them a chance to debut a new song or two.

The daytime iHeartRadio Music Festival Village is also coming back. Azalea will also be performing there, along with Childish Gambino, Kacey Musgraves, Nico & Vinz, Lil Jon, MAGIC! and Neon Trees.

“We always say the artists who perform at iHeartRadio are the biggest of the big, the leaders in every genre of music,” Tom Poleman, president of Clear Channel's national programming platforms, told Billboard. “And Iggy has really dominated the pop charts as of late. She's earned that spot."

The festival, which often features last-minute surprises, will take place at the MGM Grand Hotel & Casino in Las Vegas on Sept. 19 and 20.
