I don't think "Nyan Cat" should be tagged for this. That sample seems (both sound-wise and visual-wise) to be an autosource that just happens to have a Nyan Cat .gif: https://www.youtube.com/watch?v=pGX9oGD0NgU (sample linked)
Of course, I do not remember who it is, otherwise I would've tagged them
The metadata for the deleted Niconico upload were fetched from:
* [Nicochart](https://www.nicochart.jp/watch/sm17881960) for ID, upload date, length, uploader and tags
* Twitter search results for [#sm17881960](https://x.com/hashtag/sm17881960), which reveal that prior to changing it to "" it was called "Yukkoken". Using that for the sake of clarity
Is this creator Dead Digitizer/Eminem VEVO? (https://www.youtube.com/channel/UCkKK3_LrMdGy7Ls6isnF71Q)
I've always thought it was, but I can't find any proof to back this up so I'm avoiding adding these channels for now
