I have been looking at Diana Deutsch's "speech-to-song" illusion and I don't understand what she means by song. I have written a lot of music and I don't hear anything that sounds like a song in her samples.

Can someone clarify what exactly she means by "song"? I read through a related paper by here that seemed like it would have such a definition but didn't find one.
