For ppl with WiFi & or unltd internet via tmobile etc whom like creating playlists.

When you create a playlist even if it has 1 song. .then you have to download your playlist, once you do from than on forward if you add a song to that playlist it will automatically start downloading it. That's if you have download using cellular switched on in the Spotify app. I'm assuming it does the same over WiFi. Lmk.

same over Wifi, you can disable downloads over data if you dont have a decent data limit

We still dont know if its the same over wifi. Youre talking about disabling songs over wifi which is a whole seperate thing from what im talking about.

Btw this isnt true. It must of been a glitch, update. Etc. I was adding to my playlist amd the songs werent automatically downloading although i had download via cellur data. It might work and does the way i said but im here saying this now.
