An additional title formatting option that would be useful in Foobar2000 would be to be able to display the path in any desired manner. For example: %path1% would display the directory holding the file, %path2% would display the directory above that,... etc.

using %path2% - %path1% - %filename%

/artist/album/songname would display as artist - album - songname

The example I've shown here is relatively simplistic, but it illustrates the point well. Using the system followed by tag.exe is much more powerful but may be overkill for this application. Maybe a scheme like the one used by Monkeys Audio would be a good compromise.
Just my 2 cents.
