If there was only ONE album/cd/release you can listen to, over and over.............

Bob Dylan Blonde on Blonde

I say still his masterpiece although he has created more masterpieces than most other artists.

I couldn't count how many times I have listened to it but it must be once every two or three months at least, so starting in 1966 that is around 300 listens.

I have 8 versions and some are very good SQ as befits this icon.  The Sony gold CD is very good and hard to find now.  The SACD is also good.  The best is the 45rpm MFSL 2013 release.

@dpop      Notice you've narrowed down to All Things Must Pass.  Great choice and near the top of my list.  But where do I get a clean sounding release without the Phil Spector Wall of Distortion?  Do the masters have this mush or was it added afterwards.

+1 for Ziggy but for me it's Jeff Buckley, "Grace" (Bowie on the record wishing he'd wrote this album) and as a dark horse, Big Star, "Live At Lafayette's Music Room". Just amazing power pop that influenced literally hiundreds of bands. That music never gets old. Always fun! 

Would one Boxed set be acceptable?

Citizen Dan it would be.

Or maybe Coltrane " The Atlantic Years"

@dpop 

The closest you can get is the "George Harrison Early Takes volume 1 "

For me, it can only be...

Santana Abraxas, the original Columbia pressing.

Also for those expressing concern about something being their only choice, the OP did not state that it would be playing constantly. Only that it would be the only recording you had available. Big difference to me anyways...

Happy listening.
