Listen Together
Group Blend
Android · Windows · macOS · Linux
Your music. Your style.
A YouTube Music player for Android, Windows, macOS and Linux. Listen together with friends, blend your taste into one playlist of people, and share any track as a link that opens in the app.
Tools with real depth.
Specific features, not empty superlatives. This is what the app actually includes.
More control over sound.
A native C++ engine built around Oboe, with parametric and graphic EQ, presets, AutoEQ profiles and supported direct-output paths.
One link, any device.
Send a track and your friend gets a page that opens it straight in KatMusic on their phone, laptop or desktop.
Two looks. Your call.
Pick Classic for simple surfaces, or Modern for Liquid Glass, floating glass navigation and richer motion.
A queue you manage.
Track progress, cancel or retry, and pause Wi-Fi-only downloads on mobile data.
Intentional transitions.
Crossfade planning, BPM and phase analysis, and WSOLA time stretching.

Good to know.
Ask on GitHubWhich platforms does KatMusic run on?+
Android 10 and newer (with a legacy package for Android 7–9), plus Windows 10/11, macOS 12+ and 64-bit Linux. Every build is published on the same GitHub release.
Which file should I download?+
Use the platform tabs in the download section. On Android, the universal APK is the safe default, ARM64 is smaller for 64-bit phones, and the legacy package is only for Android 7–9.
Is KatMusic an official YouTube Music app?+
No. KatMusic is an independent, third-party project. It is not affiliated with, endorsed by or officially connected to Google or YouTube.
How do shared track links work?+
Sharing a track copies a katmusic.pages.dev link. When someone opens it, the page shows the track and asks the system to open it in KatMusic; if the app is not installed, the page stays usable with a YouTube Music fallback.
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.
How does Listen Together work?+
Create a room and invite friends with its code. The host approves who joins, and rooms include chat and synchronized playback. You can also join a room someone shared with you.
What is Group Blend?+
Group Blend is a taste match built from your KatMusic listening history. You can create a Blend, or join a friend's with an invitation code. No Spotify account is needed.
Do I need an account?+
You can log in with YouTube Music or continue as a guest. Guest mode works fully offline with local recommendations, and you can connect Last.fm in Settings to sync scrobbles.
Does every audio feature work on every device?+
No. Output modes, supported codecs and bit-perfect behaviour depend on the device, DAC, audio route and operating-system limits. The desktop builds use the host's audio stack.
Does KatMusic collect analytics?+
The project README states that KatMusic does not bundle an analytics or advertising-tracking SDK. Network requests are made to services required by the features you use.
Can I inspect or contribute to the source?+
Yes. KatMusic is GPL-3.0 licensed. The source, issue tracker, contribution guide and release history are public on GitHub.
