Part 1. How Do I Install Spotify on My Chromebook
As we know, there is not a native app of Spotify for Chrome OS now, but Spotify does offer a web player for most browsers such as Chrome, Firefox, Edge and so on. This is not activated by default though, so please follow the steps.
Step 1. Launch Chrome browser, type the URL "play.spotify.com" and press "Enter".
Step 2. If it is the first time you use the Spotify Web Player, it will prompt you to do some settings. You can enter the address "chrome://settings/content" and then make sure the option "Allow site to play protected content" is enabled under "Protected content".
Step 3. Now you can refresh the page "play.spotify.com" and login with your account. If you don't have it, you can also sign up a new one.
Step 4. To listen to songs, you just need to search and click it to to start playing.
Besides the web player, on some new Chromebooks such as Acer R11, ASUS Flip C213, Google Pixelbook which comes with the Google Play store will be able to install Android apps. The process to do that is exactly the same as on Android mobile devices. I believe that it is easy enough for you to master it by yourself, so I won't illustrate it here.
