I don't want to argue the case on the video, but I am curious. If I have legally obtained copy of a song and I play it so that people I do not know hear it is it considered illegal. Some scenarios: A) like here, I just play on my phone. Idea is that it is for myself, say I left my earphones at home, but I just need my tunes. B) I have my open headphones on, so the music is clearly audible to anyone near by me C) I have earbuds (no sound for people near by), but they get disconnected and my phone goes on speaker
