<human>:  What's the difference between a poem and a song?
<bot>: The main difference between a poem and a song is their structure and purpose. Poems typically rely on the use of language, rhythm, and imagery to communicate a message, evoke emotion, and create an atmosphere, while songs often use lyrics to tell a story or to express feelings. In addition, songs are typically set to a musical score and may include vocals, whereas poems are read aloud without any musical accompaniment.
