I might not apply to all cases - kid3 for example uses both.  Based on a brief 
look in the code and http://kid3.sourceforge.net/kid3_en.html#settings-menu, 
id3lib is used for ID3 2.3.0 tags and taglib for 2.4.0 ones, e.g. when 
converting from 2.4.0 to 2.3.0.  I don't know why though, I'm not sufficiently 
familiar with either.  Nor am I sure why one would convert from 2.4.0 to 
2.3.0, maybe for compatibility reasons with $something.  And yes, this is 
quite a corner case.
