Burning Bridges is awesome!
At first I thought it's against Richie as well. But a dig at the record company makes more sense.
- Jon's quote, that this album is only to fullfill commitments
- his quote that it ends a cycle
- his very limited enthusiasm about this album
- the whole metaphor of "Burning Bridges"
- the line from We Don't Run "I ain't afraid of burning bridges [...] like a Phoenix from the ashes",
- and the line in this songs about one more song to sell

It's just shouting out that he's sick of the record label.
But what makes me wonder...why the hell would a record company agree to put such a song on the album?
