So I am a regular listener of NTS (nts.live ), the internet radio station nominally based in Dalston and generally highly recommended. While on their Discord I found that they have an always-on jingle feed, handy for ducking into in between live shows where there's no advertising to fill and a risk of dead air. There's a public link here, and it just loops through their sonic logos (which are a little Radiophonic Workshop, a little ambient and copied by independent radio stations online the world over...)

"Stream3" is presumably chosen because there's two radio feeds.

Now... would a commercial or BBC radio station have such a back-up loop? I remember volunteering at Resonance FM many years ago and there were emergency music CDs and an automatic, tongue in cheek clip with drilling that would come on if the air went dead. But is this unique?
