"Music platforms focus on discovery but overlook emotional wellbeing."

Overview

Music for
mental health

Metle is a personal project built from my own lived experience with music and mental health — designed to support emotional wellbeing through music reflection and intentional listening.

Many music platforms focus on streaming and discovery but overlook the role music plays in supporting emotional wellbeing. There's a gap in tools that help people reflect on their emotions and practice intentional listening as part of their mental health.

Understanding
the problem

People already turn to music to manage their emotions — to unwind, feel understood, or boost their energy. While users often form strong emotional bonds with songs, they don't always have a way to reflect on those moments.

Five research questions

01
Why are young people struggling?
Social pressure, digital overwhelm, isolation, academic stress, and uncertainty about the future. Many feel emotionally overloaded without tools to process it.
02
Why aren't they getting help?
Stigma, cost, access, and the gap between needing help and knowing how to get it all create real barriers.
03
Why do they turn to music?
Music is accessible, personal, and non-judgmental. It can meet people exactly where they are emotionally without requiring them to explain themselves.
04
Why don't current platforms help intentionally?
Streaming platforms are optimised for engagement and discovery — not reflection. The goal is time-in-app, not wellbeing.
05
Why can't music also be mental health support?
A clear opportunity to build a platform that helps young people manage their mental health through music — not as a replacement for professional support, but as a daily reflection tool.

Finding
the gap

I compared leading platforms — Spotify, Apple Music, Calm — to understand what they offered and what they were missing.

What they do well
Discovery algorithms, vast libraries, personalised recommendations, social sharing, and cross-device sync.
What they miss
Emotional check-ins, intentional listening modes, mood journalling, reflection over time, and mental health framing.

Russell's Circumplex Model of Affect

To move beyond entertainment, I looked at psychology frameworks to understand how emotions are structured. This model directly inspired Metle's Mood Map — a 2D grid that lets users place themselves emotionally before and after listening.

A 2D grid where users place themselves emotionally — tracking how music shifts their state over a session.
Journalling
Capture reflections tied to specific songs or sessions — building a personal emotional history.
Reflection over time
Review emotional patterns, share moments, and understand the relationship between music and mood.
Prototype

From concept
to screens

Low-fidelity wireframes established the core flows before moving into visual design.

Blended experience
In early stages I explored features that blended music discovery with mood tracking — creating a more seamless emotional journey through the app.

Reimagined music player
I reimagined the music player to surface emotional context alongside playback controls — making the emotional dimension of listening a first-class feature, not an afterthought.
Final design

Metle in motion

The final design brings together the Mood Map, journalling, and intentional listening into a cohesive experience.

Reflection
"The gap isn't in streaming — it's in the space between the music and the moment."

Metle started as a personal frustration with existing platforms and became an exercise in designing for emotional nuance — something most product teams avoid because it's harder to measure.

The biggest design challenge was making emotional tracking feel natural rather than clinical. If it feels like homework, no one does it. The Mood Map had to be fast, low-friction, and visually satisfying.
