SPOTIFY's CUSTOM PLAYLIST SORT

The natural order of playing tracks in any playlist, (unless shuffle is turned on), uses Spotify's 'Custom' order,
whereby it will queue and play tracks listed in that order.

If a track in any playlist at the top of the list, (in pos #1), is removed from that playlist, then added back,
it will be in the list at the end, and the next track will take pos #1. Similarly, moving any number of tracks will
have the same effect.

This functionality can be utilised to create a method of using a playlist, listing tracks with the 
'least recently added' always at the top with 'most recently added' at the bottom, as way of recording the least
and most recently PLAYED tracks. Using the Windows Spotify app, will show the date tracks were added, (or played).

It's much easier to find a track from a playlist of only 50 if you return to that playlist after playing a different
one, than scrolling through a playlist of possibly 5,000 tracks.

To maintain a playlist in the form of a MIXTAPE, for example of 50 tracks, fed from a large FEED favorite tracks
playlist, you simply need remove and then replace those tracks. That will ensure tracks are not played or repeated
until all have been played.

If the moved tracks are reordered/shuffled before adding them back to FEED, then the play order will be different
for each cycle.

This can be achived maually by simply moving tracks using the Windows Spotify app, using copy, paste and delete.
Thee are also many free online services to perfom the reorder/shuffle part.

You can use Smarter Playlist to automate the process of updating the MIXTAPE and FEED.
