Singles

The first single to be released from the album was "Mondsong" which reached No. 37 in the German charts.^[8] The follow-up, "Engel der Nacht",^[9] failed to chart, meaning that three of the band's four last releases had failed to do so, a sharp decline in fortune from the band's previous track record.^[8] (See Nena/Diskografie).

The commercial failure of these two singles, one a Nena penned ballad,^[10] the other a catchy, rock tune written by Jörn-Uwe Fahrenkrog-Petersen and Carlo Karges (the duo responsible for the band's best known songs, "99 Luftballons" and "Irgendwie, irgendwo, irgendwann") provided evidence that formulae that had worked in the past would no longer reap the same rewards.

In the event and over time, it was two other tracks from the album which were to prove to be the most enduring.

"Jetzt bist du weg"

"Jetzt bist du weg" ("Now You Are Gone") was written by Nena Kerner from the perspective of a jilted lover wrestling with the accompanying emotions: not knowing whether to blame herself nor how to behave – remaining friends or getting out of the way.^[11] The song's tempo briefly quickens when she speculates about the couple potentially getting back together before slowing down again to conclude with the line, "I wish that I will finally be able to forget you."^[11] It is widely believed to be Nena's description of the split with her boyfriend, the band's drummer Rolf Brendel.^[12] The timing of events, however, do not conclusively support this belief since Eisbrecher was released in late 1986, prior to the end of Nena and Brendel's 8-year relationship in 1987.^[13] However, if the song's lyrics were autobiographical, then some of the lines (for example, "We both always wanted to be together ... but I feel so abandoned because so little remains from these years")^[11] can only reflect Nena's feelings for Brendel.

In a further twist to the question of the song's origins, in 2002 "Jetzt bist du weg" was reprised by Nena, this time with an orchestral accompaniment, as a duet with the German singer Udo Lindenberg for the Nena feat. Nena album which spectacularly rekindled her solo career in the German-speaking countries. The ostensibly curious decision to make a duet with Lindenberg out of a song with so clearly one-sided a lyric became all the more tangled when, shortly before Nena and Lindenberg performed the song live at the concert in Frankfurt marking 20 years since the band's debut release, it emerged that they had had a 6-month secret affair, when she was still going out with Brendel.^[14][15]

Whatever its provenance, the 2002 version of the song was the only track from Eisbrecher included in the 2010 Best of Nena album which Nena holds out as being her only compilation album comprising tracks which she, as opposed to her record company, has selected.^[16]

"Zusammen"

Following the death of the band's guitarist Carlo Karges in early 2002, Nena included the Eisbrecher track "Zusammen", which he had written, in her live concert setlists in 2002–2004 and again in the period since 2014, invariably as part of the finale.^{[17][18][19][20]} A live version recorded in 2015 appears on Nena's 2016 album Live at SO36. Aptly for a performer ending a concert, the theme of the song is that the singer knows nothing about the person she is singing to ("where you live ... who you are ... what you do ... who you kiss") except that she and they belong "zusammen" (together).^[21]
