Yes Dave, thats in SONG mode and your complete song data list and it is great, BUT this does not apply if you are in PLAYLIST mode and this is something i also pointed out earlier, most people would be manipulating their playlists and would need this ALL feature there instead.
You could also go to ST3 folder select all Delete and refresh database if you wanted a clean slate and thats fine, BUT there is no way to select all in PLAYLISTS where there is no other option you just cant do anything, appart from deleting a playlist and recreating the same name playlist which is not a great solution but its the way i do it as it is quicker than individually deleting songs, this does not work if you just wanted to keep a few songs and get rid of most, it would really help to have ALL in playlist when you want to filter your playlist where you need to get rid of majority of songs but not all.It would save a lot of time.
I suggested to Peter to make the EDIT function in PLAYLISTS the same as in SONG mode with slight variations to maintain consistancy and easy work flow i believe he is on to it so hopefully that will be available soon.
