I like the vocal recording, I thought for sure you would have mentioned some type of hi-pass filtering on the vocal recording; perhaps you engaged it on the mic itself.

Nothing in the recording said to my ears "oh, that's a cheap microphone". I will disagree with Mike sings here and say that had you used an SM 58, that it would have turned out better. The SM 58 would have taken more gain in your pre-amp, and it's possible that faults in the pre-amp would have shown up in the recording, so difficult to say.

I listened on Westone ES-5 in-ear monitors: http://www.westonemusicproducts.com/music/index.php/products/custom-fit/es5.html

Your point about the era in which the song was recorded is partially true. I say partially true, because Stevie recorded plenty other songs in the same era with much less mechanical sounding drums and so forth.

Again, great job on the song all around.
