I've recently been cleaning up some older MP3 collections of mine and have encountered a few instances where after I use the amazon.com details lookup, the track title fields also have the songwriter names appended.
An example of this is the following album:
Artist: The Cure
Album: Mixed Up (1990)
Amazon link - http://www.amazon.com/exec/obidos/ASIN/B00...p3tatheunive-20
The track titles ended up like this:
Lullaby [Extended Mix] - The Cure, Gallup, Simon
Close to Me [Closer Mix] - The Cure, Smith, Robert [Cure
Fascination Street [Extended Mix] - The Cure, Gallup, Simon
Any ideas why? I've never seen this in the years I've been using mp3tag before. Am using mp3tag v2.46a
