Steps to reproduce echonest remix problems with Ubuntu 12.10, Python 2.7, VirtualBox on Windows 7 Host

steps.txt

-Windows 7 64-bit Ultimate host, Virtualbox version 4.24
- Ubuntu Desktop 12.10 64-bit from ubuntu.com 7:30PM 2012-11-02
- installed following (I realize some of these have nothing to do with running these libraries, but I wanted to include anything in case something sticks out to you guys)
	- hg
	- git
	- dropbox
	- keepass
	- chromium
	- vsftpd
	- build-essential
	- ffmpeg (including ln -s .......en-ffmpeg)
	- python2.7-dev
	- python-setuptools
	- sudo easy_install pip
	- sudo pip install numpy
	- created new ssh keys
	- confirm "import numpy" works
	- confirm en-ffmpeg works
	- git clone https://github.com/echonest/remix.git
	- cd remix
	- git submodule update --init (appeared to check out the most recent, starts with 73046e...")
	- added my API key to .bashrc and confirmed it was set properly
	- sudo python setup.py install (from remix)
	- python test.py (which looks similar to the Step 4 - Make something beautiful example from http://echonest.github.com/remix/index.html#how except I used my own mp3, a filename called Rain.mp3 output to RainReverse.mp3, both in the same folder as test.py, which is two levels above remix github repo)

Here's the output:

karl@karl-VirtualBox:~$ python test.py
en-ffmpeg -i "Rain.mp3"
en-ffmpeg -y -i "Rain.mp3" -ac 2 -ar 44100 "/tmp/tmpUeMqCw.wav"
Computed MD5 of file is d68d079a0cb2571ec693cbbe834a0b89

I'm happy to provide any more information that might help debug this. I'll also try some more things tomorrow.

test.py

"""Reverse a song by playing its beats forward starting from the end of the song"""
import echonest.audio as audio

# Easy around wrapper mp3 decoding and Echo Nest analysis
audio_file = audio.LocalAudioFile("Rain.mp3")

# You can manipulate the beats in a song as a native python list
beats = audio_file.analysis.beats
beats.reverse()

# And render the list as a new audio file!
audio.getpieces(audio_file, beats).encode("RainReverse.mp3")

Thank you, my friend. Much appreciate the prompt help! This makes a happy developer!
