Spotify special behaviors

[LEFBE]

Dear all,

I currently use Spotify free version on my iPad Air, my Macbook Retina without problem.
I've installed iPhone version but here i had a special behavior.
All musics (in my personnal play list or not) cannot be played except play randomly.
Each music has a cycle icon with 3 dot such as (...)
The only options I have are:

- Add to playlist

- Select

- Add in queue

- Share

Note:

- I'm always connected to wifi network, i don't use cellular (2G/3G) network

- I've tried to remove and reinstall app without success. 

I add a (french) screenshot for better understanding 

Any idea where the problem come ?

Spotify free on mobile devices can only play playlists or artist catalogues in shuffle mode, and use radio. On-demand playback on mobile devices is a premium feature.
