Hey @Peter.Peters Is this the song?: 

I can not open the song.

It says (in the black square) that the contents is not available.

So what do I do now?

If something doesn’t appear, it may be because agreements with artists, labels or right holders for a specific market/region/country are still underway or have not been met.

Meanwhile, you can upload the song to your own mp3 section on Deezer and then you can add it to playlists. The step by step guide is here.
Apologies for the inconvenience
