With 2020 us nearing the end and turning to 2021, Google announced the new feature from google assistant, singing "new year song''. 
 
Despite that, this voice assistant can able to sing this song in variable languages but it is very horrible and cringe to listen. Google assistant will sing this for you when you say “Ok Google, sing the new year song.”  
 
The entire song is in 8-bit audio too, which fits the robotic voice of Google Assistant nicely. 
 
Google tweeted this new feature as;  

2021 is (finally) right around the corner. 🥳 Say "#HeyGoogle, sing the New Year song" to count down to the new year with Google Assistant. pic.twitter.com/baawtRgCQ7
