You know, I seem to be running into a lot of people dealing with music file format incompatibility issues. The first case was a person who couldn't burn an mp3 CD off of Itunes because all of her original media was in Apples proprietary format and the second was that some couldn't play any of their songs on their Nexus7 because they were in a .wma format. I understand the reasons for high quality media formats, but why hasn't a universal format been adopted?
