I just listened to KCJJ Iowa City online, and it has an interesting mix of music. Musically, Wikipedia classifies KCJJ as Hot AC, but this does not seem to be a typical Hot AC station. Below is a list of songs that the station played when I listened.
"Something Better" - Audien ft. Lady A (2015)
"We Belong" - Pat Benatar (1984)
"Never Gonna Leave This Bed" - Maroon 5 (2011)
"Love It When You Hate Me" - Avril Lavigne ft. blackbear (2022)
"Good 4 U" - Olivia Rodrigo (2021)
"Word Up" - Cameo (1986)
"Perfect" - One Direction (2015)
The online stream is in stereo, but the quality is lower than that of other music station streams that I have listened to.
In addition to the music, KCJJ provides local and national news, as well as local sports and weather. It also provides play-by-play coverage of local high school basketball games.
I am amazed that a full-service radio station with an interesting mix of popular music remains in operation on the AM expanded band.
