IMHO the one in -bad is ready to be moved to -good or -ugly (I'd prefer
-ugly because it's MPEG and because of the reasons you mentioned above).

It's more or less the same code as the lame plugin with just the
function names and properties exchanged.

It was moved to -ugly because it's not very useful without a decoder and
because it's "MPEG"... It could be moved to -good without problems as
the frames for all three layers and three possible mpeg audio versions
are essentially the same for the parser.
