4.4 + The title track remains the closest example of a perfect rock song, with a vocal performance that's transcendent. There's also an Eno-driven stretch of instrumental songs during the second half that's on par with some of the greatest moments of "Low." If I'm being honest, I like but don't love a couple of the other tracks (e.g. "Sons of the Silent Age") but they certainly don't detract from the overall flow.
