Spotify "Import iTunes Playlists" (for Matching/Mirroring Nested Playlists)

GOAL:  Import iTunes Playlists into Spotify.  Match iTunes playlists with Spotify playlists.  Ensure that nested playlists (hierarchies) are mirrored between Spotify and iTunes.  Links below are specifically for Mac.

PROBLEM:  Spotify removed the feature to "Import iTunes Playlists" around Feb 2018

SOLUTION

1. Download an older version of Spotify (either link below works)

2. Install

3. File > Import Playlists > iTunes


NOTE: This DOES NOT import iTunes "Smart Playlists."  Spotify unfortunately never supported this feature. You'll have to copy your "Smart Playlists" into normal "Playlists" in iTunes prior to importing in Spotify.

As of May 2020, Filehorse removed their older versions of Spotify, so I had to transition links above to spotify.en.uptodown.com.
Spotify Version 1.0.72 (from Jan 2018) and beyond downloads a generic installer which bypassed the old version code and auto-downloads the latest version of Spotify. This is exactly what we DON'T want to have happen, so we had to choose the version right before this.
