After years of trying different genres I found the best music for me: instrumental metal.
My go to artists are:
Andromida, for something hardcore
God is an Astronaut, for something melodic and chill
Outrun the Sunlight, TANK86, Modern day Babylon for the times when I want to listen to something else
anything that Spotify recommends
And my recent discovery: The HU. Mongolian band playing a mix of folk/rock/metal with a lot of throat singing. Since I don't understand Mongolian and throat singing is very uncommon for me, I just treat it as another instrument, and it can easily get me in the zone.
Nice suggestions! If you want something chill, I recommend David Maxim Micic or Plini. If you want something more technical, Polyphia and Intervals are all amazing.
