Amazon music on iTunes library
I am an elementary music teacher and have purchased hundreds of songs through Amazon digital music. Last night, I purchased a song on Amazon but this morning was unsuccessful in downloading it onto my iMac and therefore unable to get it into my iTunes library. In a lengthy online chat with Amazon, the tech finally discovered that music purchased on Amazon will not be allowed to be downloaded into an iTunes library, by order of Apple! I tried to purchase the same song from the iTunes store, but it is not available. Can someone please explain the logic of this to me?
