With the Amazon Music app, you can play or download your music library on your external SD card or Android device running Android OS version 4.1 or higher.
If the Amazon Music application isn't pre-installed on your device, you can install it by launching the Amazon Appstore app or Google Play and searching for "Amazon Music." You can also open Amazon Music Apps on your Android device to go directly to the Amazon Music installation page.
Follow the onscreen instructions to complete the app download and sign in. When signing in, make sure you enter the same Amazon account and password you use to shop for music and access Your Music Library on the web.
Once you've installed Amazon Music, swipe from the left edge of your screen or tap the Menu button to access Your Library. Music you've purchased or uploaded to your Cloud music library is available under the Cloud Library tab. Music already stored on your device and music that you download to your device's memory or SD card (available on devices running Android OS 4.4 and higher) appears under the Offline Library tab. To learn more about uploading music from your computer to your music library, go to Upload Your Music.
Note: If you don't see some of your music under Cloud, select Settings (the gear icon) from the menu, and then tap Refresh Your Music Library.
To shop for new music from the Digital Music Store, tap the Store option onscreen or in the menu.
Note: To purchase digital music from Amazon.com, verify that your device language is set to English (U.S.) through your device's language settings.
If you have an eligible Prime membership, you can also stream and download Prime Music using the Amazon Music App. If you're not seeing Prime Music on your device, app, or account, make sure you meet the eligibility requirements by going to Am I Eligible for Prime Music?
