Sure.  Make sure that if you get anything to put it in a bug report too 
(since those don't get lost as easily as mails).  I'm super busy right 
now so it'll probably be at least two weeks before I have any time to 
look at anything TagLib related.  (That goes for some of the other 
recent mails too...)
