The MP3 file is too big, so I posted it at
http://disk.jabbim.cz/ceplma@jabber.cz/music-goldberg.mp3

The MP3 does not contain an ID3 tag, so you cannot load it with mutagen.id3, 
which is
for loading ID3 tags. You should use mutagen.mp3.

The AAC file is not an MP4 file, it's just raw AAC audio with no container. 
I'll make
a new issue for a feature request to read these files, but all it will be able 
to do
is report length.

I'm still getting: mutagen.mp4.MP4StreamInfoError: 'moov not found' with trunk.

Has this been fixed?
Is there any workaround?

Issue #15 is to support opening raw AAC files. It's a marginal feature since 
there's not much Mutagen can do to those files and they're not common. It's a 
metadata handling module, and raw AAC files have very little metadata - just 
length.

If you have a problem with a file that is not raw AAC, please open a new issue 
report and attach it.
