Many Android devices come with Amazon MP3 preloaded. As one of the default apps that comes with your phone, the app has a tendency to auto-start int he background, and while the app isn’t much of a resource hog, there’s really no reason for it to be running if you’re not shopping for music or downloading purchases.
Now version 1.8.29 is available for Android 1.6 and up. The key change in this version is that the app no longer auto-starts. If you want to run Amazon MP3, you’ll have to launch it manually.
The second change is that the “auto-resume downloads” setting is disabled by default, which I imagine is intended to prevent your phone from using your internet connection when you’re not paying attention.
You can download the latest version of Amazon MP3 from the Android Market. Since there’s no easy way to uninstall the app if it came preloaded on your phone, downloading the update is the next best thing.
