There were various lo-fi business music systems. Muzak, like United Biscuits, distributed over telephone lines. There were self-contained systems. Seeburg, the jukebox maker, made one, the Seeburg 1000. It wasn't random access like a jukebox. It just played a stack of records over and over with a relatively simple mechanism.<p>Seeburg's had their own orchestra, in Chicago, and recorded their own records. They just had to buy a "mechanical license" from the songwriters, which in the US costs a fixed rate set by law. So they owned rights to the content. To protect it, they recorded it on a nonstandard sized disk (9 inches), a nonstandard hole size (2 inches) with a nonstandard speed (16 2/3 RPM, rather lo-fi) and a nonstandard stylus size (5 mils). They didn't copyright the content; that cost money back then.<p>Someone collects these obsolete machines, restored a Seeburg player, and modified a modern turntable to play them. They stream it out, legally.[1]<p>[1] <a href="https://radiocoastcom.godaddysites.com/" rel="nofollow">https://radiocoastcom.godaddysites.com/</a>
