I would ask if that lead guitar line that comes in towards the end, the one that's nice and loud, but pretty simple - is it just a HAIR flat? Might be my ears, might be worth a check.
I listened to your second version - holy cow, great groove. I liked the delayed, "telephoned" vocal effect, particularly on the "wrecking ball" part. Fits perfectly. Big compliments on the lead vocal, great singer!
One part you have is kind of a transition from verse to chorus - it's where you are going for a kind of "Eagles" "New Kid in Town" sort of vibe, with the tremolo? I don't think that tremolo helps the groove you have going. That is indeed a tiny, tiny nit to pick!!!
Want another even tinier nit? The ending, the electric guitar at the very end, the last chord, finger noises.
The acoustic guitar drives the thing from the background. The electric guitars in the background are very, very tasteful.
This is SERIOUSLY a good song. Thanks for the sharing of it. Once you get it polished, lemme know when you want my .99 cents.
cheers mate,
