Summary

SoundCloud share links generated from mobile apps use the on.soundcloud.com domain (e.g. https://on.soundcloud.com/<id>), which redirect to SoundCloud sets or tracks. Previously, playlist.IsYTDL only matched the exact domain soundcloud.com, causing on.soundcloud.com links to be classified as bare HTTP audio streams rather than yt-dlp targets.

Changes

  • Recognize .soundcloud.com subdomains (such as on.soundcloud.com short links) in playlist.IsYTDL.
  • Map .soundcloud.com subdomains to the soundcloud.com cookie jar in internal/ytdlcookies.
  • Add test coverage in playlist, resolve, and ytdlcookies.
  • Update docs/soundcloud.md to document short link playback.

Summary by CodeRabbit

  • New Features

    • SoundCloud links now support short URLs, mobile URLs, and other valid SoundCloud URL formats, not just artist-and-track links.
    • SoundCloud short links are recognized for playback, and matching browser cookies are selected when available.
  • Documentation

    • Updated SoundCloud examples to include short links and clarified how link resolution works with or without the in-app provider.

Walkthrough

SoundCloud short links are now recognized as yt-dlp inputs. Cookie lookup maps SoundCloud subdomains to the canonical soundcloud.com host. Documentation and tests cover short-link playback, classification, and cookie selection.

Changes: SoundCloud URL support

Flat SoundCloud playlists can expose API track URLs with numeric titles, so the resolver now preserves those URLs and hydrates title, artist, permalink, and duration from SoundCloud. Clarify the playlist manager save-queue shortcut in the contextual help and keybindings guide.

Verified with GOCACHE=/tmp/cliamp-go-build-cache mise exec -- make check (fmt, vet, tests).

- Around line 31-36: Update soundCloudClientID so a cache miss releases
scClientIDMu before fetching the homepage or scripts, then reacquires it to
publish the discovered ID while preserving safe cache access. Ensure concurrent
callers do not block on the mutex during discovery; if deduplicating discovery,
make each waiter independently cancellable through its context.
- Around line 143-152: Update enrichSoundCloudTracks to check each response
status before decoding, skip decoding unless it is 200, and clear the in-memory
SoundCloud client ID when the status is 401 or 403. Ensure the subsequent ID
lookup bypasses the yt-dlp cache so it does not reload the rejected ID from
client_id.json.

SoundCloud client ID discovery held its mutex during disk and network I/O, so concurrent callers could not cancel while waiting. Keep the lock around shared state only. Reject IDs after 401/403 responses, bypass rejected IDs in the yt-dlp cache, retry once with a newly discovered ID, and skip metadata decoding for non-200 responses.

Verified with GOCACHE=/tmp/cliamp-go-build-cache mise exec -- make check; added coverage for stale cached ID refresh after a 403.

Thanks for the short link fix. We need these changes before we merge:

  1. In IsYTDL in playlist/url.go, match only the hosts you need, such as on.soundcloud.com. The .soundcloud.com suffix also matches feeds.soundcloud.com, so SoundCloud podcast feeds and episodes go to yt-dlp.
  2. Move resolve/soundcloud_enrich.go and the parseYTDLTracks change to a separate PR with its own description.
  3. Remove the w hint change in ui/model/command_registry.go and docs/keybindings.md. It is not related to SoundCloud.

@bjarneo bjarneo added the question Further information is requested label Oct 22, 2026
Keep the short-link resolver change focused by removing playlist enrichment and the unrelated playlist-manager hint; the enrichment work is on a separate local branch. Match only SoundCloud page and short-link hosts so podcast feeds remain feed URLs. Verified with go test ./playlist ./resolve.
