- If you turn to this station with Jimmy Pegorino, Phil Bell, or Ray Boccino present in the car, they will comment positively, implying that this and Fusion FM are their favorite radio stations.
- The "american.gxt" data file in The Lost and Damned lists a jazz standard, Billie Holiday - "Fine and Mellow" (1939), hinting that JNR was planned, but dropped, as one of the radio stations to be updated by downloadable content.
- An advertisement for JNR says that it's at the "end of the dial", however it's not true since there's a station (K109) that has higher frequency than it.
- In the USA, FM radio broadcasts between 87.8 and 108.0 MHz, making 108.5 outside the permitted frequency range. This may be deliberate, or it could be a mistake.
