How do I remove a duplicate library set? I accidently pointed Songbird to my local and network music directories.

The easiest way to fix this is:

1. Right-click in your library's column headers and choose File Location to add it to the column list.
2. Click on File Location to resort.
3. Stretch out the File Location column -- it needs to be wide enough that you can see enough of the paths to know which ones you want to delete.
4. Shift-click on the set of songs from the source path you want to remove, right click, and select Remove.
