From time to time, Google will offer up some sweet promotions or offers for those that own a Chromecast or Chromecast Audio. The latest offers include two months of Spotify Premium, or 90 days of Google Play Music for free. Both of which will cost you $9.99/month after the offer is up. Although Google Play Music does also come with YouTube Red, which makes it a much more attractive option for those that use YouTube. Seeing as YouTube Red offers up ad-free watching of YouTube, as well as background playback and loads of exclusive content that regular YouTube users won't see.
Spotify Premium doesn't offer much over its free version. But there are no ads, and you are able to use Spotify on plenty of other devices - their free version is limited to just the desktop. Spotify has also been adding a slew of new features to their service lately, like Release Radar which was announced last week. And brings you the latest releases that are similar to the music you already listen to. A great way to find new music, without having to do much. Spotify Premium is $9.99 per month, but there is the ability to get it for $4.99 per month if you are a student.
If you own a Chromecast, it's pretty easy to get these offers and redeem them. Make sure you are on a device that is connected to the same WiFi network that your Chromecast is connected to (this way the website can find the Chromecast). Then head to the link in the source section below. It'll walk you through redeeming the offers that are available. From time to time, Google will offer up free movie rentals and much more through their Chromecast promotions. So it's definitely worth bookmarking and checking back every once in a while. These two offers are definitely worth checking out, seeing as the Chromecast is typically $35, and the Spotify offer is worth $20 while Google Play Music is about $30. Definitely worth the $35 you'd spend on the Chromecast - and many places offer it for as low as $30 or even less for a refurbished model.
