Randomize your Spotify Playlist song order
Spotify doesn't allow you to easily randomize the order of your playlists. Sure, you can play in "Shuffle" mode but that's inconsistent, it can play the same song twice, etc. And if you're trying to play from Google Assistant or Alexa, it may not allow you to play in shuffle mode. This allows you to mix up your Spotify playlist as needed.
To permanently change the songs in your Spotify playlist to a random order:
Note: this tool can be used to randomize the lines in any type of text or list as long as there are line breaks between each item. It automatically removes blank lines. To use it as a random number/name picker, just type/paste in the list, hit "Mix em up" a few times, and whichever name/number is first in the list wins!
