There are companies that produce karaoke versions of songs, if you have ever done karaoke you may often notice the music doesn't sound quite right. It is because it is a cover without the vocals. Sometimes by real people but often by computer synthesizers

So they would go to these companies and basically buy the songs, like I might go to a bookstore and buy a book.
