Play only m4a files
I have all my music on my desktop in m4a format in iTunes but I have created mp3 files which I copy into my mobile Window's devices as I get new ones. The mp3 songs are in the same folders as the m4a songs.
When playing iTunes on my desktop (which has a decent sound system), can iTunes be set up so it only plays the m4a tracks?
