Occasionally, KLOS abandoned its format to air an "A to Z" special, where songs from the KLOS library were played alphabetically by title. Running 24 hours a day (with breaks only for "Mark & Brian" and Jim Ladd's show), it generally lasted about two weeks with no songs repeated. Unlike the station's regular playlist featuring primarily classic rock hits, the A to Z also included a large number of obscure album tracks. In its final years, the A to Z special aired around the Christmas holidays. Since the dismissal of program director Rita Wilde in 2009, the A to Z countdown has not aired on KLOS. However, then-classic rock competitor KSWD, which hired Wilde, revamped the idea with a very similar, though shorter, compilation of familiar hits and deep tracks.
