The hidden track "Jam" is on all albums, but is often mistaken for the Japanese/Korean-only bonus track "Wrecking the Sphere". "Jam" is a jammed Flamenco-style tune (as the name implies) and is significantly shorter than "Wrecking the Sphere", which is a typical song.
Also released as limited and numbered seabag (1,000 copies, available only per Nuclear Blast mailorder) with digipack CD, T-Shirt and gimmicks.
