The Chykka Larva's version of Gandrayda is slow and weighty, fitting a creature that size. Much of the melody is sung by a choir, accompanied by light percussion and quiet synths. It shares a similar beat as Amorbis, musically uniting the bug-like bosses of Dark Aether. Near the end of the song, high-pitched notes are heard similar to those heard in Torvus Bog.
The Chykka Adult's version of Gandrayda shares much of the same melody and instrumentation as the larva's version. However, it is now faster-paced and features a repeating percussion rhythm like the rapid beating of wings, fitting the Chykka's much more agile adult form. Synths have a greater presence in the melody, which sounds higher-pitched and distorted like the buzzing of an insect. The high-pitched notes at the end of the larva's version are not included in the adult's version.
In Corruption, Gandrayda acts as the leitmotif of Gandrayda. It is first heard briefly in the cutscene at Generator C on Norion, where Gandrayda dispatches a group of Space Pirates. The full version is heard during the boss fight against the corrupted Gandrayda at the Proving Grounds in Pirate Research.
Gandrayda is also available in the Soundtrack Gallery. On the UK Corruption website, it is known as Track_5 in the music player. It is included in the Samus Archives Sound Selection CD packaged with the Special and Legacy Editions of Metroid: Samus Returns, titled Theme of Gandrayda.
The Corruption remix of Gandrayda borrows elements from both Echoes versions of the theme, such as the ending of the larva's version and the rapid percussion of the adult's version. Mystical high-pitched bells and whistles are given much more presence in this remix. The most notable addition is a soft female choir singing a recurring melody from the Corruption soundtrack, heard in other songs such as Rundas-mae and SkyTown. This notably alters the mood of the song, giving it a more graceful and beautiful tone.
