Mr Beast's videos have at least a spanish audio track, which funnily enough NewPipe defaults to (or did the last I checked) and NewPipe doesn't support changing the track as far as I can tell
When I first noticed this, I thought it was cool that dub-spiderman[0] migrated to using that right away, since he already went so hard with the mrbeast spanish and other dub channels. I assume it's preferable to have all of your subscribers on the one channel.
0: Jimmy's voice in the spanish dub of his channel is the same actor who dubs spiderman.
There is an option now to select the audio track and MrBeast uploads dubs in more than a dozen languages.
