Am I allowed to comment on this if I'm not a coder? I design and work on my startup (and occasionally do coding tutorials) to music anyway.

I can't do stuff with lyrics if I'm really trying to concentrate, so I stick to indie instrumentals like...

Ratatat, Delicate Steve, Mice Parade, French Paddleboat

Otherwise, old school jazz like...

Gerry Mulligan, Hank Mobley, Horace Silver

And sometimes Jamaican style ska like...

The Skatalites, Blue Beat Players, Jazz Jamaica
