Spotify

Music streaming — song search, playlist management, and cross-platform migration. Agents drive the open.spotify.com web player; the desktop and mobile apps are out of scope.

Browser Access

Requires login to Spotify in the connected browser. Premium and Free accounts both work for read/play actions, but adding tracks to collaborative playlists requires Premium on some workspaces. Sessions persist across runs as long as the browser keeps cookies.

Layout overview

The web player is divided into four persistent regions:

Region	Contains
Top bar	Forward/back, search box, account menu
Left sidebar	Library (Your Library), Liked Songs, playlists, followed artists, podcasts
Main view	Whatever was last opened: home, browse, playlist, album, artist, search results
Bottom bar (now-playing)	Current track metadata, playback controls, volume, queue button, device selector

The bottom bar is fixed and survives any navigation. Selectors that target playback should anchor on the now-playing region rather than searching the whole page.

Selector strategy

Spotify ships obfuscated CSS class names that change between releases. Two selector families are stable:

• [data-testid="…"] — most interactive controls (data-testid="play-button", data-testid="search-input", data-testid="add-to-playlist-button").
• ARIA roles + names — the snapshot tree exposes buttons by their accessible name (Play, Pause, Like, Add to playlist).

Avoid raw class selectors. They break on every release.

Search

Search lives at /search and accepts a free-text query in the top bar. Results split into tabs: All, Songs, Artists, Albums, Playlists, Podcasts & Shows, Episodes, Profiles, Genres & Moods. Each tab paginates by infinite scroll. To pick the canonical track for an ambiguous title, prefer the Songs tab and match on artist + album rather than only title.

Playlists

Playlists open at /playlist/<id>. The track list is virtualized — only rows in the viewport render. To extract the full list, scroll the main pane to the bottom in increments and re-snapshot. Each row exposes the track title, artists, album, length, and an overflow menu with Add to queue, Add to playlist, Save to Liked Songs, Share, and Open radio.

Adding a track to a playlist:

1. Right-click (or open the row's … menu) on the track.
2. Choose Add to playlist → pick the target.
3. Confirm the toast that appears at the bottom of the page; without it the action did not commit.

Library

Your Library (left sidebar) holds Liked Songs, user-created playlists, followed playlists, saved albums, and followed artists. It supports a filter input and sort by Recents, Recently Added, Alphabetical, or Creator. Liked Songs lives at /collection/tracks and is the most reliable place to bulk-export an account's saved music.

Common tasks

Search and add song: navigate to /search/<query>, switch to Songs tab, find the row, open … menu, choose Add to playlist, pick target.

Import playlist: for each input track, run search-and-add with the playlist target. Wait for each toast before moving on; back-to-back actions can drop additions silently.

Extract a playlist: open /playlist/<id>, scroll to load all rows, snapshot the table, parse each row for title/artist/album/duration.

Gotchas

• The web player throttles aggressive automation — pace clicks ~500ms apart to avoid rate-limit toasts.
• Search debounces typing; wait ~300ms after the last keystroke before reading results.
• Track titles often include (Remastered), (Radio Edit), or (feat. …) — strip these for cross-platform matching.
• Playlists and albums use the same row layout but different URLs — don't assume an ID is a playlist.
• Podcast episodes share row visuals with tracks but have no Add to Playlist option.
• "Recently Played" on the home view is a different scope than Liked Songs and can drift if multiple devices are active.
