Google is currently offering Chromecast owners a nice little bonus: two months of Spotify Premium and three months of Google Play Music access for free. The offer is good for existing owners of Chromecast or Chromecast Audio as well as those that buy a new device and sign up for the free subscription services.

You can only sign up for the two free months of Spotify Premium until September 15 but you’ve got until December 31 to register for three months of free Google Play Music access. The Spotify Premium offer is only available for U.S. citizens and you have to sign up with an email address that hasn’t been used for a Spotify Premium subscription already.

The two free months of Spotify Premium will save you roughly $20 and three months of GPM will save you around $30. If you want to buy a Chromecast in order to take advantage of this deal you’ll need $30 for a Chromecast or Chromecast Audio (both of which are currently discounted from $35).

Google sold 8 million Chromecast units between May 2016 and May this year (with 17 million sold prior to that), making Chromecast Google’s most popular hardware product. Building on this success, and in part to popular streaming services and the rise of YouTube Red, Google has shipped a further five million Chromecasts just in the couple of months since May.
