Eliminating trackname collisions in multi-CD audiobook with mutagen

I wanted to listen to an audiobook on my android phone, so I ripped it (using banshee) and copied the tracks, but "track 1" from disc 2 overwrote "track 1" from disc 2.

So this little ditty uses mutagen to rename them to "Disc 01 Track 01" and "Disck 02 Track 02" respectively.

I have since discovered that ripping this audiobook with iTunes (which consults Gracenotes where banshee consults musicbrainz) yields track names like 1a, 1b, 1c, ..., 2a, 2b, 2c, ... .

import sys
import os

import mutagen

def fix(album):
    for dirpath, dirnames, filenames in os.walk(album):
        for track in filenames:
            audio = mutagen.File(os.path.join(dirpath, track))
            print audio['album'], audio['title']
            t = "Disc %02d Track %02d" % (int(audio['discnumber'][0]),
            audio['title'] = t

if __name__ == '__main__':
    album = sys.argv[1]
