Heatmiser, I haven't read anybody else's comments.
I absolutely love this. Everything sounds gutsy, the groove between the drums and bass is insistent and gripping in an awesome "Love is the Drug" kind of way, their tones fantastic. I think the hard, roomy drums totally kick arse and the sound of the bass is superb. I like the guitar motifs and the vocal melody.
I do think the vocal has been trimmed of its warmth a bit. Perhaps a light lift in the relevant frequencies? One thing I'm not quite sold on is the sound of the intro guitar. It's a bit middly and doesn't foreshadow the sound of the whole mix when the rest of the instruments come in - there's kind of a jarring tonal shift that doesn't knit well as an intro. If you did a mid scoop, slight bottom-end lift and a 5k lift too, it would give it a little richness and sparkle and then I think the intro would work very well.
I echo the Pink Floyd reference. The song sounds nothing at all like them, but that plucky synth sound is very reminiscent of stuff on Meddle and Wish you were Here. It also reminds me a little of "The Thin Air" by Magazine. I very much doubt you've heard that track so it's purely a subjective link from me. The song could benefit from a bit of length editing.
Minor nits from me, sorry to mention them, really. I love this so much I really want to help it to be that bit better.
