it really save the cpu resource, but do not save bandwidth, if internet is slow the music still buffers, i monitored with task manager

Please add next song button on notification, so YouTube music can play next song on background. I'm using Xiaomi redmi 3 turbo

It works well on mobile, but if you turn off the screen and you're listening to a playlist on mobile YouTube, it stops at the end of the current video.

the best addon for audio only but it fails to play videos very often and needs to reload...

This extension has helped me for a long period, because i often use limited internet connection and deactvating videos helps saving bandwith.

BUT, i recently migrated to firefox and i don't know why here this extension causes a bizarre bug that is when i play a song in a playlist, shows one music but plays the audio from the next music.
I don't know why this is occuring, but is very frustrating, and only sometimes that this happens. I just use in youtube music this extension, but i have disabled it because of this error.
(And sorry, i don't speak natively english, maybe have some misspell but i have to post this review to report this)

I was concerned by comments about the extension not realIy blocking the video stream-- just hiding it. I opened Firefox's Task Manager while streaming a music video on youtube, to see if toggling Music Mode on and off affected memory & power usage. Enabling Music Mode didn't seem to reduce the CPU or Memory footprint while streaming. Too bad.

If you just want to hide images, it's good. I use Music Mode in Chrome when I'm teaching. There are lots of options on what to hide & show.
