Google Assistant has come a long way from its early days of answering simple questions about the weather. Unfortunately, it's got some way to go before it can be described as a competent singer, and I don't want you to take my word for it. Go ask it to sing you a New Year song and you'll see what I mean.
While the 8-bit music is something I can digest, the corny lyrics and robotic singing are definitely not passable. The song is accompanied by a looped video of a dancing, anthropomorphized ... something. The Earth? Perhaps the Times Square Ball? As Scott can attest, its song is possibly even worse when sung by the British English Assistant.

But hey, if you look at it from a different perspective, what better way to pay homage to 2020 than with a positively terrible song? I'm almost inclined to believe that this is intentional because the Assitant does a rather good job when you ask it to sing a Christmas carol.
You can summon the assistant to play the song by saying "sing the New Year's song" or a similar phrase. But, if you're looking to catch something more melodious, I suggest you check out Google's Blob Opera experiment — sweet tunes guaranteed.
