Although the price of YouTube Premium is not said to be super expensive, not everyone can afford it. If you have an Android phone and mainly use YouTube Music to listen to music, then this article will recommend a good alternative: “SimpMusic”, an app that allows you to listen to YouTube Music in the background without a YouTube Premium account, and also supports offline downloads.

SimpMusic is an ad-free, background-playable, and offline downloadable alternative to YouTube Music.
SimpMusic is an open source app that shares its source code on GitHub. As for this app, which can make YouTube Music ad-free and have offline download capabilities, it is impossible for Google to make it available online, so you need to manually install the APK file.
This one has a Chinese interface, so you don’t have to worry about not being able to understand the functions. I will also introduce how to switch there later. Another thing to note is that SimpMusic can only be used to listen to music, not to watch YouTube videos. It also supports 256kps high-quality music, but it requires logging into your YouTube Premium account, which is pointless.
I encountered a small problem during the test. Sometimes the music loading was slightly stuck for a few seconds and then continued to play. I am not sure if it is a problem with my network or if it is currently unstable. It’s still a beta version, so you may encounter some bugs.
According to the developer’s instructions, this product also supports Spotify Canvas, AI recommended songs, synchronization with YouTube Music, etc. I have not tried these, but those who are interested can play with it.

It also supports the lyrics function, which can be found at the bottom of the playback interface:
