Deezer announced the integration in a blog post, saying that it is already live for iOS and Android, and chief marketing and commercial officer Golan Shaked added:
We’re excited to be teaming up with Twitter to offer fans the ability to listen to music through the integration of audio cards on the platform. Given that music and social media remain an increasingly important part of people’s lives, it’s important that we continue to create opportunities where they can access both their favorite tracks and new music. This is just one of the many ways that we are enabling this.
Twitter and Deezer users: Have you tried this out yet?
