psoodonym, what do you make of the first scene of the finale?
In my view the scene illustrates that Walt has finally evolved as a person and been granted a limited chance at deliverance – a chance for some kind of redemption for a man who has demonstrated no faith.
In the first few opening seconds Walter is shown clearing a view through the driver’s window of a car covered in snow that’s just large enough to see a potential sign that it’s unlocked (by a very trusting person, ironically). I believe this is an indication that he’s already searched a number of cars this way, since he knows if he simply pulls door handles to see if the vehicles are open he could trip an alarm, and only certain cars have such a style of lock (he's still calculating). He needs to leave as minimal a trace of himself as he can. He’s already left so many tracks to himself, including, presumably, literal tracks through newly fallen snow from the bar where he must presume the DEA has traced his last phone call. The snowfall means Walt must “run blind” while, potentially, leaving a visible trace of his footsteps.
Once inside, he searches for any tools he can use to “force” the car to start, at first ignoring the most obvious location as he fumbles at the ignition switch in panicked desperation. The first thing he finds is a cassette case of “Marty Robbins Biggest Hits”. He throws it aside assuming it’s useless, though it will soon prove meaningful. Next he finds the screwdriver, a crude tool that his freezing hands can hardly use, but he manages to use it to pry off the car’s ignition column encasement, hurting his hand in the process.
That’s when Walt notices the police sirens and flashing lights. For a moment, he closes his eyes, as if abandoning his desperate hope of escape. However, in the next shot he’s opened his eyes, and then he whispers something highly uncharacteristic: “Just get me home and I’ll do the rest.” This seems to be a faithful plea and a promise to something greater than himself, something a megalomaniac like Heisenberg would never do. Only after he’s humbled himself and his would-be captors pass -- the snow on the car's windows now blinding them -- does it occur to Walt to check above the passenger sun visor (interestingly, where vanity mirrors are often located, which is perhaps symbolic of what has blinded him throughout the series). There he finds the ignition key, the literal object of his deliverance.
The engine turns over and the cassette player resumes in the middle of a Marty Robbins song titled “El Paso” (I downloaded the ep. afterwards so I could search for the lyrics):
I saddled up and away I did go, riding alone in the dark.
Maybe tomorrow a bullet may find me.
Tonight nothing’s worse than this pain in my heart.
And at last here I am on the hill overlooking …
I read the lyrics for the entire song assuming they might reveal something more. No doubt this is common knowledge by now (someone probably figured it out before the air date), but here is my interpretation for completeness’ sake:
The last episode’s title is the anagram of finale, “Felina,” which appears in the Robbins lyrics later on in the same song:
But my love for
Felina is strong and I rise where I've fallen,
Though I am weary I can't stop to rest.
I see the white puff of smoke from the rifle.
I feel the bullet go deep in my chest.

Knowing he will die (“finale”), Walt is driven forward restlessly by a sincere hope for a final act of redemption. There could be more to the song but after seeing the name "Felina" I was too excited about the find to think about more. In any case, I think of the opener as critical to the resolution of Walt’s character.
EDIT: Ok, since it hasn't been discussed here, here's
the first thing that came up in my search regarding the song's connection to Breaking Bad.
