Is there a one button delete button, to delete a song from Biab to erase all traces etc?

The only way I know is File|File Utilities...Once done, you'll have to rebuild your song list to reflect the deletion.

It's not one-button but I have always loved the menu item "nuke it". So satisfying when you have been totally frustrated trying to get a song to sound the way you hear it in your head.
