Music is in the air at WNYC, thanks to the annual "All of It" Public Song Project. 

For the second year in a row, listeners are invited to submit a song based on a work of music, literature, or film currently in the public domain. Winners of the project will get a chance to have their submissions showcased alongside professional musicians like Rhiannon Giddens and They Might Be Giants.

Producer Simon Close joined Morning Edition host Michael Hill to talk about how to get involved before May 12th, when the submission window ends.
