iTunes Tags to File Tags

[joeco]

Hi All


I'm using iTunes Match and am having trouble aggregating the tags
between machines.
I spent sometime editing the tags on my main library on my iMac.
I made a backup of the library so could return to that point.
When I updated iTunes Match it reverted back to old tags and in
doing so wrote these to the files.
So now when I click a song it disappears from my smart playlist as
it sees the tags are wrong.
Is there any way to write the tags I have in my backed up iTunes library
to the actual files so theres no discrepancy between the library tags
and file tags?


Any help much appreciated.


Thanks
