Currently in Nautilus if multiple Music files or Video files are selected and
the user "Opens" the file selection a warning pops up that "This action will
open xx windows".

This is unexpected behavior because playing multiple video files or listening to
multiple music files simultaneously seems far from general user behavior.

A more appropriate action would be for Natilus to "QUE" the files into the
playlist of the default media player for that file type. Additionally a dynamic
right-click option where the user could select "Add to playlist" might be useful
too if it doesn't intefere with the Gnome HIG.

Other information:
At this moment, adding multiple music/video files to a playlist requires the
user to launch the associated application separately and maneuver through the
dialog boxes of the application to arrange a playlist. This is time consuming
and not userfriendly.
