After all, we are in Folder Browser view :-) That's why I meant it wasn't intuitive.
The 'Queue' commands is about how the selected tracks are added to the 'playing tracks list' and is indpendant of whatever view your in.
You select 'Play Now' from the folder view and it loads all the files in that folder to the 'playing tracks list'.
You have your albums arranged in to folders so you can see the organization, but MB doesn't know that. To MB it's just a collection of files that was inside a specific folder.
When you use 'Queue Next' MB doesn't 'remember that used 'Play Now' the last time and put a whole folder in, it only sees the list of tracks and thinks you want to put the next lot of tracks straight after the currently playing track.
But then we have the 'exception to the rule'.
If you had used 'Queue Next' to load the first album/folder to 'playing tracks list'
before you started playing, you CAN queue up folders/albums and have MB add them in the proper order and then press play.
