Where do I join a discussion community concerning lost music that I received from other sources because it was not available on iTunes and now it is available on iTunes
Recently did a overall of my computer system including complete reinstallation of latest system software. I notice a lot of my music was missing. In particular, a lot of my Afro Cuban cultural stuff that was never available at App store. I received it from other sources. Now I go up on App Store and this music is available for sale there. It seems to me that something serious is going on here but I'm not ready to point any fingers. Has anyone experienced the same problem?
Mac mini (Mid 2010), OS X Yosemite (10.10.2)
