Programming
WXRT plays a very broad range of music in a format known as AAA/Triple-A (Adult album alternative). With a playlist of more than 5,000 songs from wide-ranging genres including blues, reggae, folk-rock, pop, and rock and roll, WXRT is considered a pioneer in the format. WXRT is well known for several locally produced, original programs such as Saturday Morning Flashback hosted by Frank E. Lee, Johnny Mars, and Annalisa on a rotating basis, Breakfast with the Beatles hosted by Terri Hemmert, and the Lin's Bin essay series by longtime morning host Lin Brehmer, which ran from 2002 until 2022, shortly before Brehmer's death.

Local music show "Local Anesthetic", hosted by Richard Milne, aired its final show on December 24, 2017. The final "Jazz Transfusion" hosted by Barry Winograd aired February 4, 2018, marking the end of more than four decades of the program. WXRT introduced several popular specialty programs in recent years. 'All Vinyl Saturday' began in 2016 to celebrate Record Store Day by playing individual songs and entire album sides non-stop for 12 hours. The albums selected to be played are from the personal record collections of DJs Marty Lennartz, Frank E. Lee, Annalisa, Johnny Mars, Andy Chanley and Don Davis. Due to "All Vinyl Saturdays" popularity, the feature is presented 3 to 4 times a year.
