A song that stands out from the rest is "Killer Boogie", a work which has been considered an attempt by the group to break through on the international market.

It sarcastically refers either to the band's name or to their previous works (in the sense that "as above" is written on application forms).

It is sometimes also considered to be half of the occult maxim "as above, so below," which originates in the second line of the medieval alchemical text called the Tabula Smaragdina or Emerald Tablet.

By 2001 Þeyr’s members and friends released a CD titled Mjötviður til Fóta which included songs from their second album, Mjötviður Mær and the single Iður til Fóta, both releases from 1981.

Several years later, drummer Sigtryggur Baldursson said: "The song 'Rúdolf' was supposed to be a criticism, but was really interpreted as we were Nazis.
