#21 album art can interfere with audiotrack metadata extraction

-----

I tag most of my files using MusicMatch, what I have
noticed is that with certain album art, Bitzi seems to
ignore the metadata information including album, track,
year, bitrate etc. If I remove the album art, bitzi can
correctly incorporate the metadata or if I replace the
album art it will correctly take the information. An
example of this is would be any beatles song off the
1967-1970 album in which album art is used from music
match. The end result is about 3%-5% of the songs I
submit I have to re-edit the art and resubmit. The
error rate may not sound high but when you submit 4000+
files having to find the 200+ that failed becomes a big
deal

You may have discovered a bitcollider bug. Could you
post the bitprints of some files that the bicollider
fails to report audiotrack for in the presence of album
art? I assume album art is specified in an id3v2 tag?

Thanks for the report and your efforts to contribute
quality metadata. We do hope to make that easier...
