HEy @Mohammed AL SADAT 

You should give us a little more information.

What playlist is it?

An individual that changes regularly (Monday discovery, Friday releases) or a playlist from a deezers editor?

I didn't receive any new music! Meaning that tha last new sound received from last month.  

Thank you @dee_dirk!

As our Super User said @Mohammed AL SADAT, we need more info to try to understand your case. 

I advise you to update our Deezer app and try to use Flow, check this link to see how to improve your Flow and discover new music too. 

Take care.
