Born to Die, Del Rey's debut full-length, bowed and peaked at No. 2 on the chart dated Feb. 18, 2012. The set has earned 3 million equivalent album units through Jan. 11, according to Nielsen Music, with 1.5 million of that sum in traditional album sales. The album is currently mostly powered by on-demand audio streams of its songs; in the latest tracking week (ending Jan. 11), it scored 5.5 million streams for its tracks.
The Billboard 200 chart ranks the most popular albums of the week in the U.S. based on multi-metric consumption, which includes traditional album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA). (The chart transitioned from a traditional album sales ranking to a consumption-based tally in late 2014.)
The all-time longevity champ on the Billboard 200 remains Pink Floyd's The Dark Side of the Moon, with a whopping 937 weeks on the tally to date. It's far ahead of the No. 2 title, Bob Marley and The Wailers' Legend: The Best Of…, with 504 weeks. The rest of the top five titles with the most weeks on the chart: Journey's Greatest Hits (494); Johnny Mathis' Johnny's Greatest Hits (490); and the My Fair Lady original cast recording (480).
Note: From May 25, 1991, until Dec. 5, 2009, older albums, often referred to as catalog albums, were generally barred from charting on the Billboard 200 if they fell below No. 100 on the list. Instead, they would chart on the separate Top Catalog Albums chart. Starting with the Dec. 5, 2009-dated Billboard 200, catalog albums returned to the chart, making it easier for titles, like 21 and Born to Die, to rack up significantly long runs on the list.
