Like I said, I'm not trying to be an ass, it's just a lot of "this is ok, but this isn't, but they are almost the same thing" I guess I get lost in the minutiae. It seems like its not ok for anyone to listen to "your" music, "technically". I'll probably never get it I guess.
I apologize for my tone, then. I took it as a 'gotcha' sort of comment. Basically, when you buy a song, you have the right to play it and move it to your devices. However, if you make a copy to give to someone else for them to own, then you've violated the copyright of the artist, as your friend has obtained a full copy of the song without compensating the copyright owner/studio/etc.
The use of the same Apple ID on other people's devices I'm sure is not strictly legal. The reason Apple allows you to use your Apple ID on multiple devices is because many people own multiple Apple devices on their own. within your family is a gray area, as the devices could still be considered 'yours', but you're still making multiple copies for other people that didn't purchase it. However, since this has been essentially the status quo for families from well before digital media (making a tape or burning a CD for your spouse/kid), no one is going to prosecute there.
