Most listened-to, ever... Hm. Possibly Hawkwind, the 'Space Ritual'. I played it to death in the 1970s, still dig it out every couple of years.
But the answer is Talking Heads, 'Stop Making Sense'. That's never far away.
Honourable mentions for:
The Weavers - Live at Carnegie Hall (the second reunion record, the titling was quite confusing when I lat checked)
The Cramps - Smell Of Female.
