So, why are you talking about this now? Before you were comparing
MPEG-2 audio to MPEG-1, layer 3 audio (MP3), and claimed that MPEG-2
came before MP3.

Well, of *course* MPEG-1 audio is a part of these, just like it is a part
of DVD. It's because MPEG-2 (actual MPEG-2, not MPEG-1 layer 2) audio
is a superset of MPEG-1 audio, and *includes* it. Thus, every device that
can decode MPEG-2 audio *must* be able to decode MPEG-1 audio, and thus
all MPEG-1 audio is part of these standards (which almost all specify
MPEG-2 at this point).
