The songs contained in the album are for the most part either demos or re-recordings of older Ayreon songs. "Into the Black Hole", "Out of the White Hole" and 'Through the Wormhole" are three songs from
Universal Migrator Part 2: Flight of the Migrator. For the first song, Lucassen wanted
Bruce Dickinson from
Iron Maiden; however due to Dickinson's busy schedule, it was unsure until the very last moment whether or not if he could come to Lucassen's studio and record it. As
Damian Wilson came into Lucassen's studio to provide vocals in "And the Druids Turn to Stone" for
Universal Migrator Part 1: The Dream Sequencer, Lucassen had the idea of recording a version of "Into the Black Hole" with Wilson, in case Dickinson would turn out to be unavailable. Dickinson was featured on the album version of the song, while the version present on
Ayreonauts Only is the one with Wilson, and still features
Lana Lane's backing vocals. For two other songs, Lucassen asked his friends Robert Soeterboek and Ian Parry (who had previously sung for him in Ayreon and
Vengeance respectively) to provide guide vocals for the song's actual singers, respectively
Timo Kotipelto and
Fabio Lione; those guide vocals are the ones used in
Ayreonauts Only. Another song from that album, "the New Migrator", was originally composed by Lucassen and Parry (from
Vengeance) during that time. "Temple of the Cat" is the only single released from the album
The Dream Sequencer, however Lucassen always felt unsatisfied with the final result. The version on this album is a newly recorded version, featuring Astrid van der Veen of his newly created band
Ambeon. Lucassen stated "in my opinion this acoustic version is even better than the original. This is the way I wanted this song to sound." On the album
Into the Electric Castle, the parts of the character Hippie were originally sung by the singer Mouse, but due to "unforeseen problems", his vocals were not used and Lucassen had to sing the part himself. "Original Hippie's Amazing Trip" is a medley of the parts sung by the character, but as sung by Mouse. The voice of
Anneke van Giersbergen from the original version is also present. "Beyond the Last Horizon" is a newly, "more guitar-orientated new version with
a real drummer" of the song of the same name from
Actual Fantasy, featuring
Gary Hughes of
Ten on vocals. All the parts were re-recorded, except the guitar and synthesizer solo. "The Charm of the Seer", Eyes of Time", and "Nature's Dance" are previously unreleased demo versions of the eponymous song from
The Final Experiment, with different singers: The first and third songs feature Lucassen, and the second features Leon Goewie (former member of Vengeance with Lucassen and Parry). == Track listing ==
