Which posthumous 2006 album became Cash's first No. 1 on the Billboard 200?

The posthumous 2006 album that became Johnny Cash’s first No. 1 on the Billboard 200 was American V: A Hundred Highways.

Released on July 4, 2006, the album was assembled from recordings Cash made in 2003, shortly before his death. Rick Rubin produced it as the fifth installment of the American Recordings series, continuing the stripped-down approach that placed Cash’s voice and guitar at the center of carefully chosen songs.

The album includes Cash originals such as “I Came to Believe” and “Like the 309.” The latter was the last song Cash wrote before his death and was among his final recordings. Other tracks revisit material he had recorded earlier, including “Help Me,” first associated with The Gospel Road.

American V: reached No. 1 with 88,000 U.S. copies sold in its first week, giving Cash his first chart-topper in 37 years. It is often confused with American VI: Ain’t No Grave, another posthumous album, but American V was released first and supplied the historic Billboard 200 milestone.
