Option to export ratings to text file or spreadsheet

[Ringo]

I don't like storing track ratings in the metadata because as I understand it there's no accepted standard, if at some point I switch to another application it may not recognise my ratings from Strawberry and I'll be left with a lot of metadata which is effectively junk.

What I'd like is an option to export selected metadata (and ratings) to an external text file, or possibly a spreadsheet. I would need to be able to select which metadata to include (eg Album/Artist/Title + Rating), and to exclude any unrated tracks.
