I know you have to press the music icon to have Cortana listen to a song but is there a key word that activates it after holding down the search key? Thanks.

It was reported that everything isn't working just yet with Cortana. But there will be updates.

Ask her "whats playing" and she will start listening for music.

Just say "what's this song?" If you're on LTE or fast Wi-Fi you can have the whole album in under a minute.
