Is there a way to play all songs without adding to a playlist or to the play
lis pane?

I am constantly updating my music library and have to keep creating a
playlist or adding more to the playlist when I get new songs which is
annoying when you've just put them into the library and are trying to
remember which songs are all ready there.

I just want to be able to play and shuffle all songs. I have been trying to
find this option but so far can't (hence the playlist aptly named 'All
Songs').

Any help would be much appreciated.
