Thanks for the tip. This is very close to what I was looking for, but not exactly. Maybe I'm doing something wrong but this is what happens to me:
1. When I -> right-click on the track -> Locate -> Album (or Artist) (or Genre) my default view is details, not album thumbnails. If I select all the tracks and then right-click -> Add to Playing Now, it adds them to the bottom of the Playing Now list opposed to the top of the list. Minor detail, but since my current playlist is very long, adding to the end isn't exactly what I wanted.
2. If I ->right-click -> Locate -> Album (or Artist) (or Genre), and select all the tracks and then double-click, it will do the double-click action on only the one track under the cursor opposed to all the tracks.
3. Is the only way I can get what you describe is with album thumbnails?
I just thought an easy-to-use "Play All <artist>|<album>|<genre>" would be a cool feature that no other media player has.
