A customer listened to their master and said it sounded great and clean. Then they added one concern. Pushing things out to the left and right might have cost the song some of its immersive, connected feel.
That's a real trade, and it's one AI tracks run into a lot. So instead of arguing for the first version, I built a second one and let them choose.
What width does, and what it costs
Most of the width you hear lives in the side channel, the part of the stereo image that's different between left and right. Lift the side channel in the upper mids and the mix opens up. Instruments separate. Everything sounds clearer.
Push it too far and the parts stop feeling like one band in one room. Each sound gets its own spot, and the glue between them thins out.
The change I made
The first master had a side-channel EQ lift around 4.5 kHz of about 1 dB. For the second version I cut that lift in half, to about half a dB.
That was the only change. I left the low-mid side cut where it was. No stereo enhancer, no reverb, no delay. Both versions were matched to the same loudness and true peak, so the only difference was the width up top.
The result
They listened to both and kept the first one. The extra space and stereo life won.
That's not a failure. It's the point. Half a dB on the side channel is a small move, and the only way to know which side of the line a song wants is to hear both, matched, on your own system.
How to check it yourself
Flip to mono. If a part drops back or disappears in mono, it's living mostly in the sides. A little of that is width. A lot of it is a mix that falls apart on a phone speaker.
Read correlation by band, not as one number. My note on stereo correlation by frequency band shows how. The low end should stay close to center. The top can spread.
Compare at matched loudness. Louder always sounds wider and better for a few seconds. Turn the louder version down until they match, then decide.
When to ask for it
If a master sounds clean but somehow less like your song, say so in those words. "Clean but less connected" told me exactly where to look. Then ask for a version you can A/B. You might keep the first one anyway, and that's a perfectly good outcome.
