If you just want background music, try Radio Coast.[1]. This is a successful streaming music project which annoys the RIAA because it doesn't have to pay royalties. Years ago Seeburg, the jukebox manufacturer, offered a background music service, using a special record changer which played 1000 songs over and over. The music was recorded by their own in-house musicians, so they didn't have to pay the RIAA. They never copyrighted the records, which you had to do back then to get copyright protection. Instead, they used a primitive form of DRM - the speed, record size, groove width, and hole size are all nonstandard.
All those records have been converted to files, and there's a streaming site. Hundreds of hours of 1950s elevator music.
