Well, it's the same thing when someone Copies, Streams, or Downloads Music illegally. When this happens, it is essentially the same as walking into the Artist's place of Business and STEALING from the Artist(s) and their families!
Be it known that many Musician's, Actors, Comedians, and stage performers aren't multi-millionaires. They are hard working people simply trying to make a living at what they do by grinding out opportunities like everyone else. It is important that each of us become an advocate to pay for music and not seek out ways or methods to get it for free.
Yes, copying CD's, file sharing, or Illegally downloading and streaming "tunes" is a criminal offense, but even more so it is simply down right unethical.
