I’ve recently come across a remix channel named GavinZBeats, which uploads remixes of various songs with a “Phonk” twist, except it resembles something similar to an experimental noise record.
Another one that comes to mind is VvvvaVvvvvr, which is a parody of the multiple fan channels of SiIvaGunner, and basically does the bare minimum for quality control of their submissions, one of their most recent memes is “Be an Alpha”, a song from a kids show.
