It won't play my playlist, when the first song ends it goes to "recommended

[#1]

When I'm trying to play my playlist, it switches to "recommended song" and I can't change the shuffle feature, it keeps saying I need premium to change it, I also can't use the arrow pointing to the left that goes to previous song.

Hey there!

What you're describing is the behaviour of the free tier of the app 🙂
If you wish to learn more about what Premium is, you may take a look at this support page over here!
Hope this helps. Cheers!
