Google is adding mood music to the mix as it tries to lure listeners away from Pandora, Spotify and other popular services that play tunes over the Internet.

The feature is being released Tuesday in an update to Google Play’s music subscription service, All Access, which costs $10 per month. The mood-adjustment tool initially will be offered only in the U.S. and Canada. All Access is sold in more than 40 other countries.

Google Inc. picked up the mood-melding technology in its July acquisition of a free music service called Songza. Part of Songza’s system is now being deployed by Google’s All Access so the service will make music suggestions based on educated guesses about each subscriber’s mood and likely activities at certain points in the day or week.
