Long term request : Remove dependency on Echo Nest for MP3 analysis

[Khalian]

Need to remove dependency on Echo Nest for MP3 Analysis.

ECHO Nest applies a API Key and a rate limit. Cannot scale in full production and will be fully dependent on the company.

Acoustics Engine must support in house programmatic solution to MP3 analysis.
