Metal Machine Music, subtitled *The Amine β Ring, is the fifth solo album by American rock musician Lou Reed. It was originally released as a double album by RCA Records in 1975. It was reissued on a single compact disc by BMG in 1997 and again by Buddah Records in 2000.

As a radical departure from the rest of Reed's catalog, Metal Machine Music is generally considered to be either a joke, a grudging fulfillment of a contractual obligation, or an early example of noise music. The album features no songs or even recognizably structured compositions, eschewing melody and rhythm for an hour of over-modulated feedback and guitar effects, intricately mixed at varying speeds by Reed himself. In the album's liner notes he claimed to have invented heavy metal and asserted that Metal Machine Music was the ultimate conclusion of that genre. The album made Reed a laughing stock in the rock industry while simultaneously opening the door for his later, more experimental material. Historically, Metal Machine Music is now considered a seminal forerunner of industrial music, noise rock, and contemporary sound art.

Primo Victoria (Victory to first) is the second album by Swedish power metal band Sabaton. This was the first album they released for their new label, Black Lodge Records.

War is a prominent theme on Primo Victoria, with all but "Metal Machine" and some of the Re-armed Edition bonus tracks being about specific battles or military subjects. Battles/wars discussed include D-Day/Operation Overlord (title track); Operation Desert Storm, Saddam Hussein ("Reign of Terror") and Operation Iraqi Freedom ("Panzer Battalion"); Wolf pack Hecht's attack on convoy ONS-92 as part of Battle of the Atlantic ("Wolfpack"); the Six-Day War ("Counterstrike"); the Battle of Stalingrad ("Stalingrad"); and the Vietnam War ("Into the Fire"). "Purple Heart" discusses the recipients of the Purple Heart medal.

"Metal Machine", in contrast to the other tracks, is about heavy metal, with the lyrics being built around song titles from prominent heavy metal bands such as Iron Maiden, Manowar, Judas Priest, Rainbow, Dio, Metallica, W.A.S.P., Accept, Helloween, Pink Floyd, Black Sabbath and Ozzy Osbourne.

Lewis Allan "Lou" Reed, born March 2, 1942, is an American rock musician, songwriter, and photographer. He is best known as guitarist, vocalist, and principal songwriter of The Velvet Underground, and for his solo career, which has spanned several decades. Though the Velvet Underground were a commercial failure in the late 1960s, the group has gained a considerable cult following in the years since its demise and has gone on to become one of the most widely cited and influential bands of the era. As the Velvet Underground's principal songwriter, Reed wrote about subjects of personal experience that rarely had been examined so openly in rock and roll, including sexuality and drug culture.

After his departure from the group, Reed began a solo career in 1971. He had a hit the following year with "Walk on the Wild Side", although he subsequently lacked the mainstream commercial success its chart status seemed to indicate. Reed's work as a solo artist frustrated critics wishing for a return of the Velvet Underground. In 1975, Reed released a double album of feedback loops, Metal Machine Music, upon which he later commented, "No one is supposed to be able to do a thing like that and survive."
