New · Lyric sharing
Your favourite line, made shareable.
Found a lyric that says it better than you can? KatMusic turns it into a clean, good-looking card you can send to anyone.
- Artwork-led design. The card picks up the colours of the album cover, so every song looks different.
- Everything in one image. Cover art, track title, artist and the lyric lines, with the KatMusic mark at the bottom.
- Send it anywhere. It's a regular image, so it works in any chat or social app.
Shareable cardReal screens. Real app.
Captured on Android. Swipe through the player, lyrics, library and settings.

Ask on GitHubIs KatMusic an official YouTube Music app?+
No. KatMusic is an independent, third-party Android project. It is not affiliated with, endorsed by or officially connected to Google or YouTube.
Which Android versions are supported?+
The current release offers Android 10+ packages and a legacy package for Android 7–9. Some features and media controls use alternatives on older Android versions.
Which APK should I install?+
The universal APK is the recommended option for most devices. The ARM64 package is for 64-bit ARM devices. Choose the legacy package only for Android 7–9.
How does lyric sharing work?+
KatMusic builds a card image from the track's artwork, title, artist and lyric lines. Because it is a normal image, you can send it from any app on your phone.
