Intro:

No, I didn't package the band in my py script. I was just fed up with importing, transcoding and organizing my music collection between my mac my linux server, my NAS and a USB stick (for a dumb MP3 player installed in my car). I became fed up with my transcoding shell scripts, so I ended up writing a class to process my m4a files while keeping the directory structure and tags intact.

I've started playing around with echonest's echoprint music fingerprinting and tagging the other day (gotta get rid of those duplicates :), so I've wrote in some code to interface with echoprint-codegen and their web APIs.

Played around with Celery to fingerprint and transcode massive amounts of media, and put the code in the 'other' directory. Please take a look if interested. There is a README document explaining how it works and an install.sh script to get you running in a jiffy.

Heads up: this is a work in progress and NOT production quality code... just something cool I put together these past couple days to get me through my commute (and play around with echoprint-codegen and celery:). Please feel free to let me know if you find any bugs, have any complaints or suggestions.
