Hi - I'm new to Ubuntu (and the Python scripts that go with it) and I've been hitting this error with the iTunesToRhythm script.
**Traceback (most recent call last):
File "/home/amylee/iTunesToRhythm.py", line 220, in <module>
main(sys.argv)
File "/home/amylee/iTunesToRhythm.py", line 48, in main
match = correlator.correlateSong( song, options.confirm, options.fastAndLoose, options.promptForDisambiguate )
File "/home/amylee/iTunesToRhythm.py", line 133, in correlateSong
matches = self.parser.findSongBySize( song.size );
AttributeError: 'NoneType' object has no attribute 'findSongBySize'**
I understand the concept behind fixing the issue but have no idea how to go about it. I've looked at answers to similar problems but none really help me, especially since I have no clue as to what I am doing. I've included the full script below. Thanks in advance, dudes who know way more about this stuff than I do.
