MP3 file not being recognized properly.

[crazylazylife]

I am using the following mp3 file but fleep returns an empty list for type or mime or extension for this file

info = fleep.get(open("test.mp3", "rb").read())
assert info.type == ["audio"]
assert info.extension == ["mp3"]

It returns the following error:

AssertionError: assert [] == ['audio']
