Spotify changing playlists on it's own

[Tuuki]

Sometimes when i'm listening spotify for a long time it juts changes the playlist itself

For example i listen to Artist X's playlist but suddenly spotify starts playing artist Y's song.

Is that supposed to happen?

And what's more annoying is the fact that when i change t oanother playlist and back to the original, i usually have to listen 2 sets of ads and then there's a 50% chance that spotify just starts playing another random song that isn't in the playlist.

Does this happen to anyone else because it really gets on my nerves

Free users on mobile phones, get suggested music added to their playlists. It's explained on this page.

Okay so, i won't be able to listen the music i want to listen?

Ok

Seems totally fair and nice
