I'm making a scarecrow for our scarecrow festival and what I would really like to do is have a button that a passerby can press and then a song plays. So I'd need weatherproof speaker and remote/button/something, and something that would just play one song. Is there anything off the shelf that would do this? Looking at my #emfcamp peeps because this would probably be up their alley. (bonus points if I can attach fairy or disco lights to the button that come on too)
