I'm familiar with artists using poetry in songs and selling them (Carla Bruni's CD "No Promises" which is exclusively poems by deceased poets).
I'm a musician and wanted to use two poems that I believe to be in public domain in songs to be sold via iTunes, etc.
More specifically the poems are “Heart, we will forget him!” by Emily Dickinson and "If I Could Tell You" by W.H. Auden.
Am I allowed to use these poems for commercial purposes and turn them into songs for sale?
