“Lo-fi hip-hop beats to study/relax to” might have become one of the most infamous memes to emerge out of YouTube in the latter half of the 2010s. But one of the trend’s core playlist-makers, ChilledCow, had their channel temporarily taken down by the Google-owned company.

On February 22, ChilledCow—who’s reached 4.38 million subscribers on the video-sharing platform—posted YouTube’s takedown notice on Twitter:

But the issue reached a swift resolution. Within 10 hours, the channel went back up, and ChilledCow resumed the livestream:

While it’s unclear what caused the takedown, YouTube confirmed that it was “a mistake on our side”:

The A.V. Club notes that ChilledCow is far from the only channel to stream the Study Girl. College Music has amassed 1 million followers, and the anime character briefly disappeared from the channel’s stream to raise awareness about suicide prevention.

While these playlists date back to 2013, 24-hour streams started cropping up around 2018—and ChilledCow is noted for carrying out long-running streams. When the curator’s channel was shut down, users noticed that the counter for their stream hit the 13,165-hour mark—amounting to nearly two years.

The reach of “lo-fi hip-hop beats” has become so widespread, it’s even sparked discussions in outlets like The New Yorker over the role of “chill” in the music industry.

At press time, nearly 40,000 viewers logged on to watch the internet’s infamous Study Girl return to ChilledCow’s page.

This isn’t the first time YouTube has been criticized for a takedown of a popular channel. Back in 2016, a mashup artist called BotanicSage penned an absurdist diss track against Kanye West after his peer Triple-Q’s channel was briefly taken down over a copyright strike. “ASSGORE (Fingerfückung)” went on to spark a meme that took over Tumblr.
