This is true. And dozens of big companies possibly wouldn't exist if it wasn't for the song (Spotify and loads more). Even more companies rely on bundling songs into their products in order to sell them; other products, such as phones, are often sold on the quality of playback and speed of downloading etc. Songs are an incredibly valuable thing to many, many people and organisations. Take away the song, and a lot of businesses would be in trouble. So why does almost everybody think songs should be free? Does my head in!
