In the Player-settings, I do have enabled the "play other tracks in album" i.e when navigating with the remote to a single track - and hitting the play button, I'm able to play the other tracks using the up/down button.
But when doing this from the webbrowser, it is still locked on only the specific track.
This is when I first have selected the whole album, double-click on album-art, getting all tracks on left hand side in browser and selecting a single track by pushing the play-symbol.
