Neptunium (or Nep for short) is a reimagining of Hanasu, a streaming radio player catered to Japanese and Korean music. Hanasu began as a proof of concept and a hobby project. Neptunium began as an attend to build Hanasu as a Windows 10 Universal application. Neptunium runs on Windows 10 PC, Windows 10 Mobile phones and Xbox One (via Windows 10).

• Background Audio Playback: Neptunium supports the background audio playback functionality provided by the Universal Windows Platform. That means it runs seamlessly on the platforms listed above.
• Handoff: Handoff allows you to begin playing a station on one device and get it started on another device. Nep will also stop the stream from the first device as well. This works via Cortana/Continued App Experiences (also known as Project "Rome"). This functionality is currently disabled in builds in the store because of a compiling bug.
• Bluetooth Mode (formerly Car Mode for Windows 10 Mobile): For those who like listening while on the road or using a bluetooth speaker/headset. In Bluetooth Mode, Nep can announce song names for you and even do it using the system provided Japanese or Korean voice.

I don't plan on supporting custom stations inside the application unfortunately. The part of the reason is because I wanted to limit the scope of metadata sources I need to support. The other (major) reason is because at the time, Nep couldn't read the bitrate, sample rate and channel count from streams. That means I had to hard code every stream in the application and manually test each and everyone one. Of course, with recent updates to UWPShoutcastMSS, this is no longer a limitation.

If you have a station that you want to be included, consider submitting a pull request here. Please keep in mind that the theme here is Japanese or Korean music.

Neptunium was intended to be a codename for the next version of Hanasu. Early commits referenced it as "Neptunium (Hanasu Alpha)". The name comes from the chemical element, Neptunium. It is also a backhanded reference to the main character of the Hyperdimension Neptunia series. More specifically, the nickname "nep", comes from it.

Also, I wasn't a fan of the name Hanasu. Hanasu is the Japanese verb for "to speak" which didn't make very much sense for a music application. At the same time, the verb for "listening", "Kiku", didn't have the same ring to it. In the end, I decided to go along with Neptunium as a name.

You can find Neptunium in the Windows Store via the following link: https://www.microsoft.com/store/apps/{app_id} where "app_id" is "9nblggh1r9cq" without the quotes. The reason that I am not directly linking to it is because I have the store listing set as hidden and I don't want it to be indexed in search engines at this time.

Requires the Anniversary Update (Redstone 1).

Here are some of the projects or libraries I've used when writing this:

• Crystal: My personal application framework. Provides MVVM and other boilerplate functionality.
• UWPShoutcastMSS: Used for streaming Shoutcast/IceCast stations. Fun-fact: UWPShoutcastMSS was forked from code in Nep and re-integrated as a public library.
• Kimono: A small library that contains a few GUUI controls I'm using.
• @dotMorten's WindowsStateTriggers: A library containing a variety of state triggers. Very useful for designing adaptive user interfaces.
• @danesparza's iTunesSearch: This library is used for retreiving metadata from the iTunes store.
• @avatar29A's MusicBrainz: This library is used for retreiving metadata from MusicBrainz.
• @xyzzer's WinRTXamlToolkit: Contains many GUI controls used in Nep.
• UWPCommunityToolkit
