I've been working on a really cool, unique feature called "NuPlay" and it's now ready to demo. When you add new music to your device (by downloading from a music service or copying files from your computer via USB or wifi), Music Player (Remix) will automatically detect the new songs and issue a notification. Tap the notification to play the new songs, along with the rest of your music collection sorted by the date you added them to your device.
When you add new songs to your device, in most cases you're going to want to listen to those songs, so now you can without having to manually load up the app and search/browse for those new songs. The NuPlay feature will be able to be disabled in Preferences for those who don't care to receive these types of notifications.
Here's a demo video for NuPlay: Music Player (Remix) preview - NuPlay (new song notifications) - YouTube
