If you want blah background music, I recommend Radio Coast.[1] This is an amusing exercise in copyright avoidance. Seeburg, the jukebox maker (1900 or so to 1979, bankrupt), had a side business in background music. To avoid paying royalties to record companies, they had their own orchestra and recording studio in Chicago. They'd license the underlying song, which is a compulsory license with a statutory rate. Then Seeburg made their own phonograph records, running at a nonstandard speed, with a nonstandard groove width, and a nonstandard hole size, to be played on a special Seeburg 1000 player. The player played a big stack of records over and over; it wasn't random access, like a jukebox. The records were not copyrighted, because that required a filing back when they were doing this.
So someone got one of these obsolete machines, refurbished it, and collected enough of the special records to set up a free streaming service.
