Imagine that you're sent on a one-way journey to Mars. All you can take is 4 Songs. What would they be and how would you go about choosing them. Tune in every week as Alex Hede from Woroni Radio interviews a new guest, and gives a new flavour to Music - songs that are near and dear to people of all walks of life. Listen into the linked playlist - and give it a think, what songs would you take to Mars. Produced by Woroni Radio at The Australian National University.
