Ive been using ifttt to create a discover weekly archive playlist which stores the discover weekly in a different playlist so i keep the songs, im looking for something which can do the same with my on repeat and repeat rewind playlist
Thanks for reaching out to the Community about this.
We can't guarantee how third-party services and apps would interact with your Spotify playlists. However, you can always add the contents from these playlists to a custom playlist that you've created yourself.
Keep in mind that the On Repeat and Repeat Rewindupdate every 5 days. Make sure to save the songs you like before the update takes effect.
Hope this helps. Let us know if you have any more questions.
