They should be if either the last modified timestamp or the file size
changes.

Usually, the file size will not change, since most types of tag have
extra padding space in the tag.  Most tagging programs will take
advantage of the padding and can expand existing fields or add new ones
into the padding, avoiding the need to rewrite the whole file.  Deleting
tag fields just adds to the padding.

Some tagging programs can also preserve the file modification date. 
This is helpful for keeping the 'New Music' page in Squeezebox Server
in the correct order, but it can also prevent a new & changed scan from
detecting that a file has changed.

What you'll find more than anything is that old data remains after
you've removed it from the tagging of the library.  For instance, if
you were to correct the misspelling of an artist's name and then run a
new & change rescan, the new spelling will be picked up, but you will
often still see the old artist in the library.
