July, 2010, it was the Philips's 180-CD Complete Mozart Edition rearranged in chronological order. I totally remade it last month, because: 1, I want to add more variety into this playlist; 2, About half of the Philips recordings are not available in Spotify USA. 3, There are dozens of works are not recorded for the Philips Edition, including newly discovered pieces.
After the remake/expansion, this playlists now include 2802 tracks from more than 470 recordings, covering most of the excellent Mozart interpreters and important recordings from the stereo era that I know of, and most of the tracks are now available in both Spotify UK and USA.
I tried to find all of Mozart works in recorded form. The criteria for inclusion are: 1, all works included in the Philips Edition, even a few works (like K44) are not authentic; 2, all fragments and unfinished works should be here, in their original form when possible (I have to include the completed version of the Requiem, but another recording of only the notes written by Mozart is also featured); 3, all doubtful works, unless they are proved definitely spurious (like Symphony No. 2 & 3), are included. In addition to all works listed in the main list of the Köchel catalogue, this playlist also contains these works below:

Works are arranged in chronological order based on the 6th edition of the Köchel catalogue, for works not listed there, I consulted various online sources and Hermann Abert's definite biography W.A. Mozart, but I am no expert, please leave a comment if you find any mistakes in the track order, or find anything that I left over. Thank you.

You can use this playlist to play the Mozart Game, or create as many smaller playlist as you want: just press Ctrl(CMD)+F to bring out the filter bar, then input, say, oboe:
You get all the Mozart works for oboe.
For unknown reasons, Spotify took out the stats from the filter bar, and now you cannot see those track/artists/albums numbers. The screenshots were taken with the previous version of Spotify. Also please note these sub-playlists are not as exhaustive as the main list, as tracks on Spotify are tagged by different labels using their own methods, for example: some piano sonatas are tagged as "keyboard sonatas".
If you miss the old one based on the Philips Edition, here's another Spotify playlist: Philips Complete Compact Mozart Edition - 17 Box-sets (2636 tracks, total time: 180 hours)
Happy birthday Wolfie, thank you for the music.
