On this 50th anniversary of the first moon landing, we put aside this week and seeing the worst in us to focus on what is best in us, our ability to come together over an ambitious vision and make progress towards a better future. This weekend's music thread is about the moon, the sun, the sky and the mysteries that still await us.

This weekend's music thread is about dreaming, wishing, imaginary things and places and dreamy songs and states of mind.

The theme for this weekend’s music thread is songs about and for America, songs about its people, its places, its problems and its promise.

So this weekend's music theme is inspired by the recent Democratic debates, songs about personal stories, identity, issues, agreements and disagreements.

The 2nd Democratic Debate begins tonight at 9:00pm EDT/6:00pm PDT and PlanetPOV is hosting a simultaneous live chat so you can share your thoughts and discuss the debate in real time with fellow members.
