I created a web application for people who are interested in listening to music that doesn't distract them while working.
It has 3 categories - deep work, study and creativity (each of them has completely different tracks).
The player screen is highly customizable - you can basically remove anything you don't like to see on the screen. From the settings you can also select the genres
you want to listen to. Each genre has a different theme, which is basically a looping video (can be turned off from settings as well). If you like some tracks you can add them to favorites, so you can easily listen to them later again, but If you don't like some tracks you can mark them as not interested (these will not be played automatically again)

Well, the application is free to use, but if you want to have access to all the tracks and genres then the only payment option is Bitcoin (accept payments via lightning as well).
That being said, there is a plenty of free content on the site, so it is not necessary to pay anything.
Also, this website is privacy focused so it doesn't track anything - most websites have at least Google Analytics installed.
This application is completely new, would be cool to get some people to try it out
