Do you have anything to back this up?
a few days EARLIER this was released in Israel by KAN (television chanel)..
I know you probably can't speak hebrew but here is a song made (vocals/lyrics/music) by AI, of two dead singers who are very famous in Israel (Zohar Argov and Ofra Haza).. It is convincing
I think if it wasn't in hebrew language(and to be honest, Israeli) it would have been on HackerNews or at least on reddit somewhere.
There is also some really good ones of Curt Cobain. The AI group is a Tel Aviv startup calle Aiode.
