The sum encompasses his solo and group album and song releases.

Following his May 17 death, Chris Cornell's catalog of albums and songs, both solo and with his various bands, surged by 552 percent, to 32.7 million in combined sales and on-demand streams (up from 5 million) in the week ending May 18, according to Nielsen Music.

In terms of on-demand streams (audio and video combined), Cornell's songs collected 32.5 million streams in the week ending May 18, a gain of 549 percent (from 5 million in the week ending May 11). His catalog of albums sold 38,000 copies (up 1,732 percent from 2,000), while his songs sold 144,000 downloads (up 2,222 percent from 6,000).

Meanwhile, several songs and albums by Cornell populate Billboard's rock charts (dated June 3), including seven new entries on the Hot Rock Songs survey. His Hot Rock Songs presence is led at No. 7 by Soundgarden's "Black Hole Sun," from 1994's Superunkown, which also becomes the band's first No. 1 on the Hard Rock Digital Song Sales chart, moving 17,000 downloads (up from 1,000 the week before). The song also drew 4 million U. S. streams (up from 1.3 million). "Sun" marks the band's best rank on the Hot Rock Songs since "Live to Rise" peaked at No. 4 in June 2012.

(Hot Rock Songs began in 2009. Older songs are eligible to re-enter or debut if up noticeably in multiple metrics and rank in the top 25.)

In addition to "Sun," Soundgarden's "Fell on Black Days" (No. 16) and "Spoonman" (No. 19) appear on Hot Rock Songs, along with tracks by Cornell bands Audioslave ("Like a Stone," No. 10; "Show Me How to Live," No. 21; and "I Am the Highway," No. 25) and Temple of the Dog ("Hunger Strike," No. 18).

The top seven spots on Hard Rock Digital Song Sales belong to Cornell-affiliated titles (as do 12 of the chart's 25 positions).

Meanwhile, Superunknown debuts at No. 5 on Top Rock Albums (17,000 units, up from 1,000). Titles from Audioslave, Temple of the Dog and Cornell solo also make various lists, including Audioslave's self-titled album (No. 10, 11,000) and Soundgarden's Badmotorfinger (No. 19, 7,000).
