I posted this on reddit today, but am keen to get more feedback! I've been working on this project for the past few weekends — I decided tonite to pop it onto github in barebones form.
Basically, it allows you to stream lossless audio files from your own personal amazon s3 bucket. I've been using it as my main player for home and work, and I'm quite happy with the results.
Built with node, electron, webpack, ES6/babel and postcss. I know it's a bit of a steep setup to get an s3 bucket going, but that's life.

There's a bit of background on the project via the readme if you are interested. thanks!
