purchased aac files mixed with m4p files
Hi, I haven't been able to find an answer to this question that I have. On 12-01-2012 I had purchased the soundtrack Full Metal Jacket now when I click get info and the file tab kind is listed as purchased aac audio file and all tracks are listed like this however when I go into the folder where the files are stored tracks 2-8 are listed as MPEG-4 audio file (protected) (.m4p) while tracks 1 and 9 through to 15 are listed as ,m4. never encountered this before was apple still using the DRM at that time or is it something else? I've never had an album purchase from Itunes that is like this in terms of different files on a single album
