Alabama, Brooks & Dunn and Rascal Flatts each walked away from the 2015 ACM Awards as winners -- but not in any of the usual categories. The three country music acts were honored by the Guinness Book of World Records for their outstanding careers.

Alabama earned a world record for Most Consecutive Wins as Entertainer of the Year. The group took home the trophy for five consecutive years, from 1981 to 1985.

Brooks & Dunn, who returned to the stage on Sunday night (April 19) for the first time since their split in 2010, set two world records: Most Wins for ACM Duo of the Year and Most Consecutive Wins for ACM Duo of the Year. The two have won the category 16 years total throughout their illustrious career, including eight consecutive wins beginning in 2001. Brooks & Dunn also received a 50th Anniversary ACM Milestone Award during the live broadcast.

Rascal Flatts, who were nominated for an ACM Award for Vocal Group of the Year this year, set two world records as well: Most Consecutive Wins for ACM Vocal Group of the Year and Most Wins for Vocal Group of the Year. The trio won the trophy seven times in a row, from 2003 to 2009.

The audience at the 50th ACM Awards also helped set a world record. The event, held at AT&T Stadium in Arlington, Texas, hosted 70,252 fans, earning it the new record for Highest Attendance at an Awards Show Broadcast.

Brad Paisley and Miranda Lambert were also honored by the Guinness Book of World Records over the weekend. Paisley won for Most Consecutive ACM Male Vocalist Award wins, while Lambert won for Most Consecutive ACM Female Vocalist Award wins. Lambert took home the ACM Award for Female Vocalist of the Year again last night, already breaking her own record.
