Right, next year I'm going to code up something to prevent the same file being imported multiple times (within the same session). This'll solve this problem, and the other confusing delete-from-playlist issue.

It'll have to do something a bit cleverer with the tags. Consider the following:

1. Import a file
2. Edit the tags (on the file, using Winamp, e.g.).
3. Edit the tags (in emplode)
4. Import the same file again.

Should it use set of tags (2) or (3)?
