The Amazon MP3 application enables you to purchase music online and listen to it while on the go as it can be stored locally on your Android phone. The application has been updated to version 2.0.10 bringing features and fixes to the table.
First of all, automatic downloads will now only download new purchases. Playlists for latest purchases and latest uploads are now updated in order to match the Cloud Player for Web. As far as fixes go, the new version solves the bug causing skips in streamed music and it also improves stability with large download queues. Head over to the Android Market or follow the source link to update your client to the latest version of the application.
