Admittedly, these vocals are heavily processed. That is appropriate for the style and genre of where the song lands. It is "radio Pop/Country" - and has to compete with all the other radio Pop/Country out there. It is a "modern" treatment of vocals. That is certainly "not for everybody" and is not appropriate for all types of music. Not many people (certainly on these forums) write or produce music aimed at being "more commercial". The singer-songwriter and old style Country and Rock can get by with far less processing - to remain sounding "vintage"...

But, it doesn't hurt - and might well help - for folks to train their ears to hear what has been done with these vocals to place them where they intend to go (radio, modern ears and earbuds). The use of as much delay as reverb is likely new to some. As mentioned, the level of soft sections to loud sections is important in any recording. The use of harmony through so much of the sing, while again, not necessarily right for all genres, is interesting - also the fact the much of it is a third below the main vocal...

The vocals are clean and crisp, but not with a bunch of jacked-up high EQ (which is a mistake many make) - so they remain "warm" and still cut through the mix - a worthy goal in any vocal recording.

It is nice to have the vocal-only recording for comparison. We got little of that in the past. And "little tricks" learned from studying something like this can translate into something "new" in your own music - and give it a "fresh" sound. If all you ever do is "the same old thing" then your music will remain sounding like "the same old thing".
