I always listen to music while working + noise-canceling headphones.

My criteria for the most productive music:

The best music is music that "flows" together naturally (like full albums and sets), rather than a playlist on shuffle. When music effortlessly transitions, I get lost in my code/writing/whatever.

I also find YouTube to be the best way to listen to music because they have the full DJ sets and albums, and their recommended is really good.

Here are some playlists/sets that always get me in the zone:

^^ A running list. If you know of other music I might like please send it to me!
