Regex Editor & Tester

Matches individual SoundCloud track URLs in the format https://soundcloud.com/username/track-name, capturing the full URL in a named 'track' group. Negative lookaheads exclude reserved system paths (sets, playlists, stream, discover, charts, settings, etc.) so playlist/set links and non-track pages are rejected. It also supports optional secret tokens (/s-XXXXX) for private track sharing plus trailing query parameters. Useful for validating or extracting single track links in link parsers, scrapers, or embed generators.
