To me it sounds like you are sorting the playlist to be a certain way in the desktop app (soring the date colum as newest on top)
If any of the column headers at the top of your playlist have a green arrow, you will need to press it twice to view the playlist the way everyone else will see it (without the sorting). Then, I recomend re-sorting the playlist by newest on top. Then create a new playlist and copy the songs over. Then delete all the songs from the current playlist, and then copy the songs over from the new playlsit you created. That way after you copy them over, the newest ones added are at the top without sorting turned on. If you rely on the right clicking Add to playlist option to add new songs to playlsits, it adds new songs to the bottom of the playlist. I suggest instead when listening to a song to drag it into the playlist, and then drag it up to the top of the playlist.
