Album Length

A Spicetify extension that surfaces the length of each track’s source album / EP inline in playlists, Liked Songs, and the Queue — so you can see at a glance how long the whole project is without clicking into the album.

Why

If you keep playlists made of tracks pulled from different albums and EPs, Spotify shows you the track duration but never the album duration. To know whether a song belongs to a 22-minute EP or a 70-minute LP, you have to click into the album. This extension shows that number where you can already see the album name.

Features

• Inline badge appended to the existing Album cell in tracklists (e.g. Currents · 51m).
• Works in Playlists, Liked Songs, and the Queue — toggle each surface independently.
• Format options: 42m / 1h 23m, 42:13, 1 hour 23 minutes, or auto-hybrid.
• Tooltip mode if you’d rather see the length on hover.
• Optional color-coding by album length, with customizable colors and tier boundaries.
• Singles auto-hidden — when a track is the album, the redundant badge is suppressed.
• Album durations are cached indefinitely (album lengths don’t change). Cache lives in Spicetify.LocalStorage.
• Settings live in the profile menu (top-right avatar dropdown → “Album Length”).

Install

Manual install:

1. Copy album-length.js into your Spicetify Extensions folder:
   • Windows: %APPDATA%\spicetify\Extensions\album-length.js
   • macOS / Linux: ~/.config/spicetify/Extensions/album-length.js
2. Enable it:

   spicetify config extensions album-length.js
   spicetify apply

Display modes

Inline (default) shows the length appended to the album name. Tooltip mode hides it until you hover the album cell.

Tooltip on hover

Settings

Open the Spotify profile dropdown (top-right) → Album Length.

Badge colors

With color-coding enabled, badges are tinted across four length tiers — by default green under 30 min, yellow to 60 min, orange to 120 min, red beyond. Each tier’s color and the boundary between tiers are editable: pick from the swatch or type a hex value (#rrggbb or #rgb shorthand). Boundaries are kept in ascending order automatically, and Reset colors & thresholds restores the defaults.

How it works

Each tracklist row contains a link to the album it came from (/album/<id>). When the row is rendered, the extension extracts that id and fetches the album’s track list — first via Spicetify’s internal Cosmos endpoint (wg://album/v1/album-app/album/<id>/desktop), falling back to GraphQL (getAlbum) on newer Spotify builds where the legacy endpoint is gone. Track durations are summed and the total is persisted to Spicetify.LocalStorage indefinitely. A single MutationObserver on the main view container handles re-injection when Spotify re-renders rows.
