You can get browser extensions to do it for all media controls on any site. YouTube's "Premium" for 3x is laughable when it's an internal browser function.
Premium is for up to 4x, not just 3x
That’s an amusing observation.
Likewise, YouTube’s “premium” feature of not displaying ads is laughable when displaying content is literally an internal browser function.
I pay anyway, because I was going to pay for an on-demand streaming music service anyway.
Another fun thing is if you use an extension you can fast-forward through the advertisements too. For some channels I use around 3.5x playback speed.
