control deezer on phone via alexa with sony headphones

I am on the free month at the moment and if I cancel or not depends on the answer from here.

I have a Android phone, with Alexa as the assistant, and a pair of Bluetooth Sony headphones. When I use Amazon Music I can control it via either saying Alexa or pressing a button on the headphones.  So Alexa, play 80s music or something like that. Can't seem to do it with Deezer, I started Alexa and Deeezer apps up, but still don't work.

Am I missing something or is it not possible?

It works okay on my Echo units at home, but that is a different thing.

I have been using Amazon prime music for a few years, but decided I wanted a bit more choice in the music I play, Deezer is a bit cheaper than the others, if i go for a 12-month plan. 

Also, I noticed that some of Deezer stuff, don't seen to be as good sound quality wise as Amazon Music when played on my Echo units, I know Echo units are not the best speakers, but they are fine for what I need. Just wonder why the difference.

Thanks for any help
