STZ Lyrics Overlay
A synced-lyrics overlay for Windows, rebuilt in Python and independent from Rainmeter. It uses GSMTC to detect the current media session and LRCLIB to fetch lyrics when available.
Key Features
GSMTC + LRCLIB Sync
Reads the Windows media session (GSMTC) and fetches lyrics from LRCLIB, with incremental synchronization when synced LRC lyrics are available.
Tray Controls
System tray icon with quick actions to show/hide the overlay, toggle click-through, reload lyrics/config, and open the cache folder.
Presets and Context
Supports layout presets such as Context (2+2), with per-preset preferences for position, lyric color, always-on-top, and animation.
Timeline Smoothing
A local smoothing clock reduces jitter/freezes reported by some players and improves lyric/UI timing fluidity.
Local Cache + Startup
Persistent LRU lyrics cache with index.json, local logs/cache folders, and an optional Start with Windows setting.
