Miranda Lambert, Florida Georgia Line and many of country music's biggest and brightest got together for the 50th Annual ACM Awards on Sunday night (April 19).

And considering its golden anniversary, the Academy of Country Music decided to go big and take it to one of the largest places in the U.S. -- the AT&T Stadium, the home field of the Dallas Cowboys. Hosted by Luke Bryan and Blake Shelton, the stadium was packed to the brim and actually broke the Guinness World Record for most attended live award show of all time, which Bryan and Shelton announced at the top of the show.

Some of the night's early winners were Miranda Lambert, who won Song of the Year for "Automatic," Little Big Town, who received the award for Vocal Group of the Year, and Direks Bentley, who nabbed the Video of the Year award for "Drunk on a Plane." Florida Georgia Line walked away with two (so far) -- Vocal Event of the Year with Bryan and Vocal Duo of the Year.

The 2015 ACM Awards are also honoring seven artists who have shaped country music to what it is today with the 50th Anniversary Milestone Award. This year's honorees are Garth Brooks, Kenny Chesney, Miranda Lambert, Taylor Swift, George Strait, Reba McEntire and Brooks & Dunn.
