SoundCloud Downloader — anyo

Features:
✅ Download any SoundCloud track in mp3 format
✅ Adds metadata (artwork, artist, title, composer, genre, year, description & source url)
✅ Works without an account, a Go+ subscription, or even being logged in
✅ Works on private tracks shared through a secret link
✅ Works whatever language your SoundCloud is set to
✅ Customizable file name format (see Preferences tab in about:addons)
✅ Supports both progressive and hls transcoding formats
✅ Lightweight (~29 KB), no background process

How it works:
The file is built in your browser, straight from SoundCloud. Nothing goes through a server of mine, and there's no third-party site in the way. The add-on only asks for access to soundcloud.com and for storage to keep your filename format.

Good to know:
⚠ mp3 at 128 kbps, one track at a time. No playlists or albums.
⚠ SoundCloud has started locking some tracks behind DRM. Those can't be downloaded by this or any other extension. You get a clear message rather than a broken file.
