The newly discovered state found by BaBar decaying to Ds pizero is
apparently a c sbar p-wave state, although its mass is far from what
theorists had predicted.  This leads us to a re-examination of models
for mesons made of one light quark and one heavy quark.  These systems
are analogous to the hydrogen atom, but with the fine structure and
hyperfine structure enhanced.  A rather general analysis can be done
without resorting to detailed numerical calculations.  It shows that
it will be hard to explain simultaneously the spectrum of Ds states
and their decay patterns.
