Just like the title suggests, what gets your vote for the perfect song? Feel free to list as many as you think are worthy. I'll start -- Richard Thompson's "1952 Vincent Black Lightning". It's just superb. I think it's the vivid lyrics and storytelling... but the melody and structure is quite nice as well. No matter how many people cover it, it's still great. I'm hoping this thread gets folks introduced to new music, songwriters, etc.
