Cover art for I'm on Fire lyrics by Bruce Springsteen

If you watch the music video for this song, it becomes pretty clear. Its about liking someone that's unavailable. Basically, Bruce is fixing this beautiful woman's car, who flashes her wedding ring and lives in a big house. He goes to her house to drop off the keys, and hesitates ringing the doorbell, before just leaving the keys in her mail drop and walking away sadly. There's nothing he can really do about the infatuation. I love this song!!
