How might I gather all the songs in my music library (maintained in iTunes) on Mac OS X 10.8.5 with ID3 title tags (I guess? their titles in iTunes) that consist of 4 random capital letters. Or all the ones whose titles are 4 characters long, case insensitive, or mixed character types... if they're just 4 in length... anything that could help me narrow it down to that specific criteria. My whole iTunes music library is contained within one folder, to be clear, so anything that could identify these for me within a particular folder will work. Thanks much.
