The Dark Side of the Moon.

The Dark Side of the Moon. It spent 741 consecutive weeks on the Billboard 200 — that’s over 14 years. From 1973 to 1988, it never left the chart. Not even close.

The album didn’t just sell; it became background radiation in American homes. People bought it, their kids discovered it, then their kids bought it. Repeat. It’s still the longest consecutive run in Billboard history for any album by a single artist (the only longer run is the My Fair Lady soundtrack, which doesn’t count for this question).

That’s not a trivia stat you’ll forget.
