Sonarah is a Spotify-powered playlist matching tool for people who care about flow, mood, and intent — not just collections of tracks.
Instead of generating playlists automatically, Sonarah helps you curate by comparison: you take a playlist you trust and match it track-by-track with new music that feels right in the same position.
"If you like this track here, what would you put next to it?"
Sonarah is built around one-to-one matching:
- You choose a reference playlist
- For each track in that playlist, you select a matching track
- The result is a new playlist that mirrors the original’s energy, mood, and flow — without copying it
This keeps humans in the loop while still accelerating discovery.
Sonarah’s experience is intentionally structured around playlists as creative units.
From My Playlists, you can:
- Browse playlists you follow or own
- Search for playlists
- Create new playlists
- Unfollow or delete playlists
This is the starting point for all other actions.
Inside a playlist, you can:
- Search for tracks
- Add tracks
- Remove tracks
- Reorder tracks
This step is about shaping the reference material. The quality of the matching experience depends on how intentional the source playlist is.
This is Sonarah’s core interaction.
- Displays the original playlist
- Tracks are matched in order, one-to-one
- Each reference track corresponds to a single match slot
- The matched playlist is built progressively as selections are made
- Presents candidate tracks sourced from Spotify recommendations and search
- Tracks can be previewed using a built-in web player
- Selection is based on perceived fit, not algorithmic scoring
The goal is to create a playlist that feels right in the same sequence as the reference.
Sonarah does not auto-generate playlists. It supports deliberate, track-level decisions by the user.
Matching is about contextual placement within a playlist, not finding globally similar tracks.
Playlists are treated as authored objects with internal logic, pacing, and narrative.
Traditional recommendation systems answer:
"What else might I like?"
Sonarah answers:
"What belongs here, at this point in the playlist?"
This makes Sonarah especially useful for:
- Rebuilding or reinterpreting existing playlists
- Translating a vibe across genres or eras
- Long-form listening sessions where sequencing matters
- DJs, selectors, and intentional listeners
Sonarah is:
- A playlist curation tool
- A discovery aid grounded in context
- A way to reason about playlists structurally
Sonarah is not:
- A one-click playlist generator
- A ranking or scoring engine
- A passive recommendation feed
- Sonarah relies on the Spotify Web API
- Spotify’s recommendations endpoint is deprecated, which limits the quality and longevity of automated candidate generation
- As a result, discovery currently depends more heavily on search and remaining recommendation surfaces
These constraints directly shape the current product experience.
