Where is AllOnTheOne.mp3?

Still confounded on this. Thought maybe it could be a permissions issue so tried running add_blips using sudo and get following errors. Not sure if they will shed any light.

$ sudo python add_blips.py DrumnBangStereoMix.mp3 DrumnBangStereoMix_blips.mp3 beats bars
Password:
blipping beats.
blipping bars.
en-ffmpeg -i "DrumnBangStereoMix.mp3" -y -ac 2 -ar 44100 "/tmp/tmpE5TdpN.wav"
