[1] The title song includes all of the band members, but the single contains a bonus track called "While Your Lips Are Still Red", on which Olzon and the guitarist Emppu Vuorinen do not play.

[2] On 24 August 2007 the Nightwish's official website reported that "Amaranth" had already achieved gold status in Finland two days after its release, meaning sales of over 5,000 copies.

[3] On 6 September the official site also announced that Amaranth had reached the top of the charts in Hungary[4] and Spain too.

[5] "Reach" was the original title for "Amaranth" when Nightwish began recording the demos for Dark Passion Play.

[8] The video alternates between the band playing underground and scenes of a story of two boys who find a fallen angel.

It begins with the boys playing by a stream, having a good time, but when one of them looks up from his toy boat, he sees an angel lying on the other side, unconscious and bleeding from her eyes.

The track listing was revealed on the website of Nightwish's official fanshop on 21 June, as the pre-sales began.
