As a life-long Rush fan and been in Rush cover bands, I don't think I've ever liked a Rush album on first listen... but they grow and grow on me.
Headlong flight: On first listen, I am undecided. Can't understand the words... don't like the vocal sound (on the streaming version at least). song structure seems random and disjointed. No real hook.
2nd listen, after looking at lyrics: love the lyrics, starting to find the hook, liking the vocal lines. Like the guitar parts that sound like Bastille Day and Cygnus, although they seem a little "sloppy" like someone said, if that's possible for Rush.
Next day listen, getting used to the song structure, although it still doesn't seem to "stick" with me, like Caravan and BU2B, especially Caravan hit me with a hook.
HF sounds like Vapor Trails to me, lots of good bass lines and vocals, thick guitar chords get a little boring without lead lines or keyboards. Too long for what it is, not progressive.
Will have to see how the rest of the album shakes out.
