Beautiful app!
I have used it with music therapy clients by itself, and along with a guitar, rainstick and winds chimes to create a very peaceful setting. I can easily see it being used in a classroom/music room to provide background sounds for books or story telling. I would highly recommend FreeSong2 to use for yourself when you need a calming moment, for your young kids to give them a successful tool to channel their musical creativity, and for use with special needs populations to promote a successful and beautiful experience. I cannot say enough good things about FreeSong2!
