I second all the above---no $ for mucked up sound.   I guess they don't want anything that could be at some later time converted to a new format--sort of planned obsolence.  Read the following to see exactly what your ears have been telling you.  Notice the way MP3 messes up the mid range, not just the highs.  If they cared about sound quality but for some reason feel the need to have a lossy format,  ogg is clearly the way to go.
