According to the law, none of the actions listed above is an infringement. A person in European Union is entitled to play CDs freely at home or in his car, lend the original CD to anyone and make "a few" copies of it for his own or his family members to use and even give an occasional copy to his friends without violating anyone's copyright.
Then again, playing copyrighted music for commercial purpose of any kind - were it in or outside an enterprise's premises, at a show or gig, on the radio or TV, you name it - is due paying to the copyright owners' association, which is a legal body authorized collecting the fees and delivering the money to the members according to the official regulations and agreements.
That's basically how it is in the States. If you use music in a business, whether it be background music or whatever, someone has to get paid. Businesses typically pay the licensing fees as part of a subscription fee to Muzak (or whichever satellite-delivered music service they use).
--But if you're playing music for yourself or for a few friends and there is no money or like-kind exchange for the music, you're okay.
