spogo is a terminal-based Spotify client written in Go that provides full control over playback, library management, search, and user listening data. It authenticates via browser cookies (sp_dc/sp_t) instead of the official OAuth flow, allowing it to bypass rate limits by using Spotify's internal web API endpoints (Connect/GraphQL) alongside the public Web API. The architecture is modular with multiple engine backends (connect, web, auto, applescript) and a clean CLI interface built with Kong. It features robust output formatting (human, JSON, plain), comprehensive error handling with documented exit codes, and extensive test coverage. While the tool is highly functional and well-crafted, its reliance on undocumented internal Spotify APIs and webpack hash resolution introduces fragility that may require maintenance as Spotify's frontend evolves.
