But first, let’s see what Lucie has to say


Lucie, 28 years old
Casual Blind Test lover on Deezer
I love playing Blind Test on Deezer, it’s my go-to way to unwind after a long day! But sometimes, it feels a bit... lonely. I wish there were more ways to interact with my others while playing. Competing, laughing, sharing those ‘I can’t believe you didn’t know that song!’ moments, that’s what I’m totally missing.
A real challenge from Deezer
A real challenge from Deezer
During my bootcamp at The Design Crew, I was super excited to take on the role of Product Designer alongside 2 amazing teammates. We got to work on a real challenge and we had the chance to share our ideas with Alexis Czornomaz (VP Product Design & User Research), Victor Cartier (Product Designer) and Octave Aribaud (User Researcher) from Deezer.
Let’s start with a bit of context before getting into the heart of the topic.
Music Streaming Service
Deezer lets you listen to songs from all over the world. You can create playlists, follow your favorite artists and get personalized reco based on what you love!

GOAL #1
Keys to Engagement
Understand the features that make a multiplayer game engaging
GOAL #2
Where It Hurts
Explore the main pain points in the multiplayer gaming experience
GOAL #3

Imagine challenging your mutuals to a blind test and they can see it instantly within the app. With this new feature, proposing a challenge becomes fun and interactive. Let’s see how it works!

01
HOME SCREEN
The term “mutuals” invites competition. A rocket icon means someone challenged you, "new" marks fresh connections, and "+" lets you start a challenge.

DUEL ON COMMON MUSIC TASTE
To challenge someone, everything revolves around mutual musical tastes. So, users can test each other’s knowledge of the songs, creating a fun experience.

WHAT’S NEXT?
To go further
With this solution, Lucie can have more fun playing with her friends! By adding duels and challenges, we make the experience more exciting and interactive. If we had more time, we’d add a few extra features to make it even better.
Add Shaker groups to the Blind Test game
Choose the playlist after selecting who to challenge
Choose the playlist after selecting my friend
Enhance competitiveness through the ranking
Play with non-Deezer users
A final word ?
Looking back at my project as a Product Designer at Deezer, I’m amazed by how much I've grown. By embracing a non-linear process, our workshops sparked unexpected and valuable insights. I learned the true power of storytelling in UX and the importance of committing to one strong solution rather than getting lost in endless options. This journey has completely reshaped my approach to design!
IN THE END
Feedback
At the end of this project, we had the chance to present our case to 5 professionals in Product Design: 3 from Deezer and 2 from The Design Crew. It was a great experience sharing our journey, challenges, and insights with them. Their feedback and perspectives were invaluable, helping us refine our approach even further. Here’s some constructive feedback they provided.
