Here's what I'm currently listening to:
Generally one of Spotify's 'Focus' playlists or Brain.fm.
Tends to be a podcast. Current favourites are The Tim Ferriss Show (quite long), The Way I Heard It (very short, by Mike Rowe), and Revisionist History (by Malcolm Gladwell).
General / Cooking / Other
I've been on a James Blake kick recently while working on tasks that don't need a ton of focus. Juanes, Queen, and 90's hits are especially fun while cooking.
