I’m currently listening to n0theen. It’s a netaudio stream, meaning that it’s like radio over the internet but without moderation. Just one song after another.
They say that they are only playing “opensource audio”. I’m not sure if it’s the correct term, because there is only very few open-source audio on the web. Open-source in the sense, that you can actually get the sources of the song, like stems, samples or project files. I guess what they mean is music published by netlabels which you can normally get as free downloads.
There is music from lots of genres. Most of the songs are instrumental and kind of electronic: Minimal, IDM, etc., but there’s also Rock. It’s great for just playing in the background while you’re doing other stuff. Like me writing this post.
On the website you can find a playlist with the last 20 tracks which were played. In case you liked a song really much, go to the website, look it up and search for it on the internet. Chances are that you’ll find a free and perfectly legal download.
I haven’t heard them playing any annoying music so far, so maybe you’d like to give it a try.
