My Question or Issue

Ok I have been using Spotify since it was available on the PSN firstly as a free service but subscribed a short while ago.

I have other devices I'd like to use it on like the phone I set up this free account on in order to post here as well as tablets and smart devices throughout my house.

I have the ability to control Spotify on my PS4 from my phone but I'd like to use my premium account while out and about as well as on other devices around my house that don't have the ability to connect to my PS4 like my Amazon Echo 8.

Can this be done?

Do I need to set up an account and subscription for each device?
