Phoebes,
I’m thinking you have another mix possibility in you for this super-poppy (comin-in-hot-at- (-9LUFS) love song.
I read your critique and then listened. My first impression was that no, you’re not lacking air in the intro KB/ BS/SYNTH line. But then the vocal appears and it can’t compete (frequency bandwidth wise) with the music. That contrast of a dull vocal against the music might just be the crux of your identified lack-of-air problem. Your singer might be emphysemic, but I have another diagnosis worth pursuing.
I put a Mid / Side EQ on your track and soloed up just the Mid thinking I could add a high frequency shelf to bring the vocal’s airiness to the forefront. Listening with that EQ in place revealed what I think might be a big contributor to the problem. The vocals in the middle are not very loud. It sounds like the two vocal performances are interfering with each other time wise. It’s phase-y. It’s a cool, effective sound when used for creating width on a stereo track, but if you had a solid foundation of vocal center panned and then hard panned the two additional vocal takes L and R, you’d have a wide, lush, vocal presentation that would be easy to brighten up to save your patient and bedazzle your audience.
To be fair, I am not an actual doctor, but I do like analogies.
