Fails to recognize certain valid MP3s
_parse_header in MP3Info.py fails to recognize certain MP3s that are entirely
playable (thus causing positron to report "not a supported audio format").
mp3id returns valid MP3 header for those tracks which report "not supported".
I can't send an example MP3 for copyright infringement concerns, but if someone
has an emusic account, several of the tracks from Richard Thompson's "The Old
Kit Bag" give this error. E.g., track #2.
