Damn I had noticed a lot of series doing it, but I guess it's wider than I thought!

The Magicians overdid it though. It's not a musical episode, iirc it's like 2 seasons

Edit: just to be clear, I still watched those 2 entire seasons, because the story is genuinely that good, plus I was invested. But I really wish they hadn't gone musical, it really messed with the mood of the series.
