The song:
(Intro)
Amaj7, riff 1,  E, G#5

Amaj7, riff 1,  E, riff 2, D5

(verse 1)
Amaj7
the useless drag of another day
                                  E   G#5
the endless drags of a death rock boy

Amaj7
mascara sure and lipstick lost
                           E (riff 2)  D5        Amaj/riff 4
glitter burned by restless thoughts of being forgotten

(Chorus 1)
F#5         Amaj   E(vii, riff 3)
and in your sad machines
F#5       Amaj     E(vii, riff 3)
you'll forever stay
F#5       Amaj   E(vii)       D5          Amaj7
desperate and displeased with whoever you are
Amaj7            (main riff)
and you're a star

E  G#

(Verse 2)
Amaj7 (this one holds for 4 measures)            E     G#5
somewhere he pulls his hair down over a frowning smile
Amaj7                                                      E (riff1)D5 Amaj
a hidden diamond you cannot find a secret star that cannot shine over to you

(Pre Chorus)
c#5     D5      Amaj/riff 4
may the king of gloom,
c#5   D5   E(vii)/riff 5
be forever doomed

(Chorus 2)
F#5         Amaj   E(vii, riff 3)
and in your sad machines
F#5       Amaj     E(vii, riff 3)
you'll forever stay
F#5     Amaj  E(vii, riff 3)
burning up in speed
F#5    Amaj     E(vii)       D5    Amaj(let chord ring and feedback)
lost inside the dreams, of teen machines

(interlude, guitar with sustain, other guitars play glissandos around Amaj)

then you're giving up

(Chorus 3)
F#5         Amaj   E(vii, riff 3)
and in your sad machines
F#5       Amaj     E(vii, riff 3)
you'll forever stay
