Play in MP3tag context menu

On my win 7 pro x64 system I have managed to change the context menu in Explorer to open music files in foobar instead of in Windows Media Player (WMP). This change is reflected in the context menus of other programs (e.g. Total Commander) as well. Unfortunately, the "Play" entry in MP3tag's context menu still insist on opening the selected file(s) in WMP. How can I get MP3tag to also use foobar?

I think you have to change the default program for that file type. Use the explorer and windows means to achieve that.
