  Utilizing a QCD Coulomb gauge Hamiltonian with linear confinement specified
by lattice, we report a relativistic many-body calculation for the light exotic
and charmed hybrid mesons. The Hamiltonian successfully describes both quark
and gluon sectors, with vacuum and quasiparticle properties generated by a BCS
transformation and more elaborate TDA and RPA diagonalizations for the meson
($q\bar{q}$) and glueball ($gg$) masses. Hybrids entail a computationally
intense relativistic three quasiparticle ($q\bar{q}g$) calculation with the 9
dimensional Hamiltonian matrix elements evaluated variationally by Monte Carlo
techniques. Our new TDA (RPA) spectrum for the nonexotic $1^{--}$ charmed
($c\bar{c}$ and $c\bar{c}g$) system provides an explanation for the
overpopulation of the observed $J/\psi$ states. For the important $1^{-+}$
light exotic channel we obtain hybrid masses above 2 $GeV$, in broad agreement
with lattice and flux tube models, indicating that the recently observed
resonances at 1.4 and 1.6 $GeV$ are of different, perhaps four quark,
structure.
