Hello again, In music maker, if you want to add a recorded track, go to the bottom section, select "file manager" locate the track you want to add, and drag it to any open track.  As long as music maker recognizes the file format the track should appear on the time line.  Music maker will not recognize .m4a files from itunes.  I have read that there are m4a to mp3 conversion applications available but have never done it so I can't reccomend anything.  Good luck
