Suggestion for library Auto-Update. NOT like iTunes.

Is there a way (add-in or otherwise) to have Songbird monitor a directory (or directories) and automatically add any new files added to that directory to the Library? Maybe a refresh button would be better so it doesn't lag every time you open the player.

This would be a reverse of the iTunes way. I don't want my music player moving/copying/sorting my files. I have a specific way of naming and sorting. I want to be able to drop 20 new albums, each in their own folders, into my E:\Music dir., hit refresh and have them show up in my Songbird library. It should also remove non-existent files from the library (as an option?)

I imagine there are many 'open-sourcers' out there that would appreciate this.

Thanks
