I downloaded Little Fox Music Box just the other day because it was Apple's Free App of the Week. It's a very nice looking app. There are three songs (London Bridge, Evening Song, and Old MacDonald). There is an option to have the song sung along with the text or to sing karaoke-style where the words are highlighted in time with the music, but the user needs to provide the singing. There is also an area called Fox Studio which has "found sounds" such as bottles, teapots, spoons, etc. for the user to use to create music. I see limited use for this app in the classroom unless you teach preschoolers, but I know my preschoolers at home will love it, so it will keep it's place on the iPad.
