From that Snopes link: > Does this mean that everyone who warbles "Happy Birthday to You" to family members at birthday parties is engaging in copyright infringement if they fail to obtain permission from or pay royalties to the song's publisher? No. Royalties are due, of course, for commercial uses of the song, such as playing or singing it for profit, using it in movies, television programs, and stage shows, or incorporating it into musical products such as watches and greeting cards; as well, royalties are due for public performance, defined by copyright law as performances which occur "at a place open to the public, or at any place where a substantial number of persons outside of a normal circle of a family and its social acquaintances is gathered." So, crooning "Happy Birthday to You" to family members and friends at home is fine, but performing a copyrighted work in a public setting such as a restaurant or a sports arena technically requires a license from ASCAP or the Harry Fox Agency (although such infringements are rarely prosecuted). That's what I wanted to know. Actually, I wanted to know about people being sued over singing "Happy Birthday to You" to their child, but I suppose the answer is more or less given in the fragment I just cited. Your other link is about the Amazon Kindle. Hardly a parent reading a book out loud to their child. It's followed by some highly opined speculation that you can't read a book to your child, but that's not a source of somebody being sued for reading a book to their child. I suppose that also didn't happen, since it would be more or less the same as singing "Happy Birthday to You" to your child, which your source Snopes already said was okay.
