Neither MP3 nor WMA uses Coding Technologies' Spectral Band Replication 
technology, which essentially doubles the coding efficiency of the core 
codec. The HD Radio codec (HDC) _does_ use SBR. So the comparison that you 
are making is not very relevant. If you compare HDC to anything, it should 
be to HE-AAC (aacPlus).
