I was hoping to find a bunch of unicorn-themed stuff, but I only found three things. Oh well. We'll take a look at those three items, along with some other neat items that I found. Just a few weeks ago, you couldn't swing a dead cat in there without hitting unicorn stuff. I had a girl and her mom in line behind me at the checkout. The girl was buying something "for [her] ASMR." Her mom said, "What's ASMR?" I almost spoke up to answer, but then I felt like that might be creepy, so I just stood there and kept my mouth shut. :)
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
