One week shy of its chart anniversary, Post Malone’s Stoney finally touches No. 1 on the Top R&B/Hip-Hop Albums chart (dated Dec. 16) and shatters the record for the longest climb to the summit. The set tops the chart in its 51st week on the list, eclipsing the previous 40-week benchmark set by Guy’s self-titled LP in 1989.

Stoney earned 37,000 equivalent album units in the week ending Nov. 30, according to Nielsen Music, rising from No. 2 to No. 1.

Stoney, released on Dec. 9, 2016, has endured thanks to a spaced-out series of hits in the past year. The album’s “Congratulations," featuring Quavo, had a slow but steady rise in the first half of 2016. The song debuted on Hot R&B/Hip-Hop Songs the same chart week (Dec. 31, 2016) that Stoney made its chart premiere, but reached the top 10 for the first time some four months later, on the chart dated April 29, 2017. “Congratulations” ultimately peaked at No. 5 for five weeks as it banked 21 straight weeks in the top 10 before departing the region in September.

The Top R&B/Hip-Hop Albums chart ranks the genre’s most popular albums of the week in the U.S. based on multi-metric consumption, which includes traditional album sales, track-equivalent albums and streaming-equivalent albums. Thus, on-demand audio streams and song downloads of Stoney tracks directly benefit the album’s chart placement.

In addition, Stoney earned a bonus push when a live performance of the album cut “I Fall Apart” went viral in September and sparked massive streams and new radio airplay for the tune. “Apart” entered Hot R&B/Hip-Hop Songs at No. 24 in October and currently sits at No. 9 – its highest rank yet -- for a second frame.

Plus, Post Malone’s current monster hit, the standalone single “Rockstar” (featuring 21 Savage), sits atop Hot R&B/Hip-Hop Songs for an eighth consecutive week. The huge momentum behind the collaboration has likely encouraged new listeners to explore his back catalog. Stoney, Post Malone’s only studio album to date, would be the key beneficiary.

As Stoney’s persistence pays off, here is an updated look at the 10 longest treks to No. 1 on the Top R&B/Hip-Hop Albums chart, dating back to its launch on Jan. 30, 1965:
