The major problem is that the xdg-user-dirs are mostly localized (i.e. with a 
german setup $HOME/Music becomes $HOME/Musik). The actual path is written 
into
        $(XDG_CONFIG_HOME)/user-dirs.dirs
default:
         ~/.config/user-dirs.dirs
where one for example finds:
        XDG_MUSIC_DIR="$HOME/Musik"

So Amarok has to get the XDG_MUSIC_DIR value at every startup, since of course 
this can change (i.e. the user changes his system language from german to 
english).

Amarok starts -> reads the value -> scans collection -> user can deactivate 
the directory -> which drops the whole "read the value" thing.
