I'm happy to say I've almost run out of suggestions, mostly due to the fact that D-V has actually released many of my suggestions.
I can only think of a few unreleased titles now, and the rest are supposedly off the table like Jerry Reed, Johnny & Edgar Winter, Paul Simon, etc.
Maybe Burton Cummings' 1976 self-titled debut?
There are FIVE Mac Davis titles to choose from and all of them have pretty decent mixes and all have at least a hit or two.
I would imagine any of the Elvis titles are all locked down and untouchable.
Still wouldn't mind some Dolly Parton or the single Waylon outing.
