It's a beautiful, musical serenade at a LA Metro Stop that went viral this week.
An employee with the Los Angeles Metro recorded the woman, seen above, who sounds like an opera singer at the Metro Purple Line Wilshire/Normandie stop.
The woman has not been identified but the LAPD Twitter had this to say in a caption: "4 million people call LA home. 4 million stories. 4 million voices...sometimes you just have to stop and listen to one, to hear something beautiful."
Gorgeous!
