Station Diaries #1 - Start of Something New

861 Words

With how accessible internet connections are these days, the explosion of streaming almost feels like a natural progression of the way we consume media. In the case of music, we’ve never experience so much convenience since all you have to do to listen to your favorite album is to launch Spotify, type its name and click play.

That said, this convenience comes with important and potentially dangerous pitfalls such as giving Spotify data about what you listen, when you listen and where you listen. This should be enough reason to consider an alternative if privacy is at all important to you, but if that’s not the case maybe the case for artist profits should be. Spotify pays, at maximum, US$0.0084 per stream to the holder of the music rights (which includes the record label, producers, artists, songwriters, and who knows what else). This means that 1 million streams, an impressive feat if you ask me, generates US$7,000 (which the artist might not get even half of).

With those concerns in mind I decided to start Station, a self-hosted music streaming service, in hopes of encouraging people to start buying music once again or suport their favorite artists in some other way (like going to concerts!). The idea is that you set it up once and are on your way to having your very own Spotify, running wherever you’d like. You and other users can add music to the library to be shared with eachother effortlessly, without giving up the convenience of modern streaming services.

Welcome to Station Diaries, a series of posts where I’ll detail progress on this admittedly ambitious project.


I’ve been writing JavaScript for a good 3 years now and my first instinct was to use it for this project as well. It took some convincing but I decided to try .NET Core and it’s been a good (albeit rocky) journey, even if I still think it’s weird to write code in an environment where so much is abstracted away from the programmer.

Since I’m already learning an entire new language and framework, I decided to also go with a different approach with regards to databases. I have had so many terrible experiences with ORMs in the past that I couldn’t justify giving yet another one a try, which led to using stored procedures / functions for everything that deals with the database. Creating a user? SELECT * FROM createuser(email, password). It is definitely weird writing SQL as functions, especially considering there is no linting / completion / syntax checking whatsoever, but it’s honestly not much different from writing JavaScript and running your code with pretty much no confidence that it will run. I must say I didn’t miss the feeling of shock when you run code and it works, though.


Some key characteristics I believe will make Station a pleasure to use and maintain are:

  1. Plugin system The application was designed from the start to work in a plugin system. By default it has no knowledge of how and where to acquire tracks, it only parses data returned from plugins. This allows users to extend the upload system with whatever sources they’d like (Soundcloud, YouTube, etc) without risking the application’s legitimacy. Station in no way wants to promote piracy, but there are completely valid reasons to acquire music from the listed sources, so a plugin system puts that responsibility on the plugin loaded by the user.

  2. MusicBrainz integration Music organization is a nightmare. There are so many edge cases that I could spend the time it takes to finish a Dream Theater album and still not be done. Because of that, Station uses the MusicBrainz database as the ultimate source of truth; if a track cannot be found on it, expect undefined behavior and dead animals. This can be a burden for a user, but it can be easily fixed by adding your entry to the MusicBrainz database, improving Station for yourself and MusicBrainz for everyone :)

As of writing this post, I have mostly figured out the song creation part which I believe to be the most crucial and sensitive part of the application. The current process of uploading a new song works as follows:

  1. `SongWorker` class receives a response from a plugin, which includes a byte array representing the music file, it’s name, artist, album, duration and, optionally, a MusicBrainz ID.

  2. Worker tries to find more information about the track on MusicBrainz. If it fails, it aborts the operation entirely.

  3. Creates Artist, Album, Song and Upload objects accordingly and returns the new Song object to the user.

The logic is simple, but it involves a lot of (admittedly ugly) code that I’m hoping to clean out later.

Currently I’m working on the authentication system using ASP.NET’s AuthenticationHandler and a system of claims. There are no permissions in place at the moment, as my current goal is to get an MVP working as soon as possible.

That’s all I got for now. Thanks for reading this far and if you’d like to contribute feel free to check Station’s repository on Github or contact me at Issues, PRs and comments are, as always, welcome :)
