Premise How to play m4a files?

You need an SACD player to playback the SACD layer.  You might have one already as some DVD players and the PS3 can play them.  If you did, it would say SACD somewhere on the front or have the symbol found here on the front:  http://en.wikipedia.org/wiki/Super_Audio_CD

Nothing to do with age Chuck.  Good recordings are good recordings

I was going to say, it's not like Chuck is 20 years older than me or something  I do have that Beach Boys album on DVD audio.  I think Fry's sells that one too.
