 It failed to hit the "Billboard" Hot 100 chart due to the rules of a physical/commercial release of the single at the time, but it still peaked at number 24 on the Hot 100 Airplay chart and number nine on the Mainstream Top 40 chart.
 The song was included on Soundgarden's 1997 greatest hits album "A-Sides" and appeared again on the 2010 compilation album "Telephantasm".

 The group contributed three songs to the C/Z Records compilation "Deep Six" in 1986, before Sundquist was replaced by Matt Cameron.
 After two extended plays (EPs), Soundgarden released its debut full-length album "Ultramega OK" in 1988, on which Cornell was credited for songwriting on all but one of the eleven original songs. "
Louder Than Love" followed in 1989, on which Cornell was credited solely for writing seven of the album's twelve songs (and co-credited on four of the other five).

Audioslave was an American rock supergroup formed in Los Angeles in 2001.
 The four-piece band consisted of Soundgarden lead singer/rhythm guitarist Chris Cornell and Rage Against the Machine members Tom Morello (lead guitar), Tim Commerford (bass/backing vocals), and Brad Wilk (drums).
 Critics first described Audioslave as a combination of Soundgarden and Rage Against the Machine, but by the band's second album, "Out of Exile", it was noted that they had established a separate identity.
 Audioslave's sound was created by blending 1970s hard rock with 1990s alternative rock.
 Moreover, Morello incorporated his well-known, unconventional guitar solos into the mix.
 As with Rage Against the Machine, the band prided themselves on the fact that all sounds on their albums were produced using only guitar, bass, drums, and vocals.

 The band dissolved in 1997 and reformed in 2010.
