Audio keychain bot

What can do this bot?This bot can recognize the musical key and the bpm (beats per minute) of any song.
To start, send me an audio file in mp3 or wav format smaller than 15 megabytes.
This bot uses audiokeychain.com to recognize the songs. Both the audiokeychain client and the bot is written by @danogentili.
