CHATBOT: As an AI language model, I don't possess the cognitive abilities to create or produce music on my own. However, it's completely possible to write a rock song using a piano, just like Tom Petty did. Many rock songs have been written on the piano over the years, and it's a versatile instrument that can be used to create a wide range of sounds and styles. It all comes down to the creativity and skill of the songwriter and the tools available to them.

CHATBOT: Sure, here's a shot at a Tom Petty inspired rock song: Verse 1: There's a feeling in the air, can you feel it too Gonna grab my guitar, gonna sing it for you The world's spinning fast, it's hard to keep up But we'll hold on tight, never gonna give up Chorus: Won't back down, gonna keep on keepin' on Won't be held captive in a world gone wrong We'll rise up, fight with everything we've got We won't stop, no we won't stop Verse 2: The road's ahead is windy and long But we'll keep on moving, we'll stay strong We're the hopeless romantics, the underdogs too But we'll keep on rocking, until we break through Chorus: Won't back down, gonna keep on keepin' on Won't be held captive in a world gone wrong We'll rise up, fight with everything we've got We won't stop, no we won't stop Bridge: We'll run through the fire, face the storm We'll keep on dancing, won't conform With every step, we'll play our part Rising up strong, right from the heart Chorus: Won't back down, gonna keep on keepin' on Won't be held captive in a world gone wrong We'll rise up, fight with everything we've got We won't stop, no we won't stop Outro: We won't back down We won't back down No we won't back down.
