This is a great question I think. I have a CD player hooked up in my coop, with CD's I've burned just for them. All very soft rock, like CSN&Y, The Eagles, Barkley James Harvest, The Doobie Brothers,ETC. I also have Ackerman, Michael Hedges, George Winston, etc, for soft guitars and no vocals. My DH thinks I have went a little nuts, but they are much calmer when the music plays softly in the back ground. If any one else is playing music, let me know. I need to add 'new tunes' to the list. Thanks!!
