Real-time lyrics for Spotify on Windows, using Musixmatch and ReadProcessMemory (yikes).

Lyrics

Lyrics for Spotify, in real-time. Uses Musixmatch as a backend, but it actually works.

Features

• Minimalistic UI with stay-on-top and auto-scroll features.
• No input; just launch it and let it do the rest.
• Song lyrics are automatically cached, for your offline needs.

How does it work?

1. When a song is playing, the title of the main Spotify window is scanned, and the title / artist are extracted from it.
2. Several times per second, the memory of the Spotify process is scanned to find strings that match a timestamp (0:00 or 00:00), and all these strings are cached.
3. The program attempts to find the timestamp that is most likely to be the "current song position" timestamp, using the following criteria:
   • If a new song just started playing, we select the timestamp which is the lowest, but which was high before (since the text likely went from 3:42 to 0:00).
   • If the same song is playing, we select the first timestamp that increased by 1 since the last analysis (since a song will likely go from 3:41 to 3:42).
   • If no song is selected this way, we take the last timestamp that matched either one of the previous conditions.

spotify-lyrics-windows's Issues

Highlighted lyrics (big and white lyrics) auto-skip to the end.. In other words the word (end) is highlighted and so autoscroll wont work throughout the song.

Amazing program tho! Please fix!
