Oh yes, I forgot to mention:

VSB versus SSB versus "real" AM:

VSB is NOT the same as SSB with carrier.   VSB 
operates as DSB at lower modulating frequencies.
As you raise the modulating frequency the signal
becomes SSB.

The reason VSB can sound better than SSB with
carrier is that most of the modulating power is in the
lower modulating frequencies and the usual diode
demodulator handles that relatively well.
