I recently got into the piracy community, and discovered a great open source app for Android that allows you to stream music for free from YouTube music! It’s called ViMusic and it’s one of the best free music apps imo. It has a beautiful and customizable interface and it actually has a music recommendation algorithm which is one of the main reasons people still pay for music subscriptions like Apple Music instead of pirating. This app has been really helpful to me and I hope that it can be to you too :)
There’s also innertune (yt music, like vimusic) and xmanager (Spotify)
Just be aware that while xmanager itself is open source, the patched spotify apks it downloads and installs can be filled with obfuscated malware and you have no way of knowing.
The patches aren’t open source.
