I wanted to verify that all of my songs in my iTunes library existed on my local filesystem, and vice versa, so I turned to python to help me out. I exported the entire Music library from iTunes as an “m3u” playlist called “Music.m3u”, then used python to compare and contrast. Code below:
#!/usr/bin/python
import os
library_path = '~/Music/iTunes/iTunes Music/'
library_path = os.path.expanduser(library_path)
m3u_songs_file = open('Music.m3u')
m3u_songs = m3u_songs_file.readline().split('\r')
m3u_songs = [ song for song in m3u_songs if '#EXT' not in song ]
m3u_songs = [ song for song in m3u_songs if song != '' ]
local_filter = [
'/.DS_Store', '/.iTunes Preferences.plist',
'/Mobile Applications', '/Ringtones'
]
local_songs = []
for root, dirs, files in os.walk(library_path):
for file in files:
songpath = os.path.join( root, file )
skip = False
for filterstr in local_filter:
if filterstr in songpath: skip = True
if not skip: local_songs.append(songpath)
missing_from_local = [ song for song in m3u_songs if song not in local_songs ]
missing_from_m3u = [ song for song in local_songs if song not in m3u_songs ]
print "songs in iTunes but not found on local filesystem:"
if not missing_from_local: print "\tNONE!"
for song in missing_from_local:
print "\t",song
print "songs in the local filesystem but not in iTunes:"
if not missing_from_m3u: print "\tNONE!"
for song in missing_from_m3u:
print "\t",song
