LIGHTNING IN A BOTTLE

A metal-tinged anthem about using Jev properly. A robot voice opens with Diogo Almeida's "We have lightning in a bottle, and yet it is not useful"; Doom's E1M1 riff (a nod to TypeSafe's Doom launch demo) carries the song; a vocoder sings the jev-axi pattern — "the code decides what code can decide, Jev takes the rest". 150 bpm, 64 bars as written; Jev plays 7–16 sections (1:30–3:25), and the cap narrows its choices from section 12. It plays once and ends on an E power chord, a crash and a shotgun blast.
