Here are a few tools I have been using this year. I absolutely love these open source apps and I think you might too.

Amberol

Amberol is a music player with no delusions of grandeur. If you just want to play music available on your local system then Amberol is the music player you are looking for.

Beeref

BeeRef lets you quickly arrange your reference images and view them while you create. Its minimal interface is designed not to get in the way of your creative process.

A simple and elegant open-source markdown editor that focused on speed and usability.

MicroPad (μPad)

A powerful note-taking app that helps you organize + take notes without restrictions.
