Something they talked about a lot in the Tom Petty documentary was how Petty’s lyrics are simple but leave things open ended for the listener.
“I’m learning to fly, around the clouds
But what goes up must come down”
I feel like the song could be about countless different things which is great. In the doc Petty said he didn’t necessarily write songs about certain people or events in his life. Some could view his lack of authorial intent (or political agenda etc) as impersonal or even amateur, but I think it just makes the songs more universal and emotionally accessible.
