Does anybody remember this mashup of different megalovania / sans au songs?

Last year i remember watching this youtube video that was just 100+ version of megalvania fan songs. It started with the original megalovania and switches every few seconds, while on the screen flashed different versions of sans based on AUs. Is it possibile that materia took it down? It'd be a shame. Anyhow, if you remember what it's called, tell me please.
