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.
