19th St Bart is right by Pandora, which (per glassdoor) seems to have a number of jobs around $100k. Cutting the cost and time of a commute is worth paying for.
That still seems way low to me. A qualified software engineer or designer can command a six figure salary remotely, thus eliminating a commute and the need to live in an expensive city. If Pandora is doing $150k for mid level developers then I'd say it's worth it, but not a penny less.
