Music business is a fascinating thing, isn't it? It all starts with a song. You want to make money with that song, don't you? So you buy rights to protect that song. You hire a producer and a band to play and record that song. You get a publisher to track every time that song is played. You create merchandise to market that song. You travel around so, when face to face with the masses, you can share that song. You advertise on several forms of media so you can tell the whole world about that song.
