Not trying to prove I'm the biggest dinosaur in the zoo,
but I do like TEXT windows ("Terminal",etc)

and to play my saved/local   mp3 files,
mpg123     floats my boat
   ....especially to random-play-everything-from-a-file-list",
            or just " cd ArtistDeJour ; mpg123 * */*  "  or such. 

mpg321 is not in base Mint (nor other release's base generally) pkg list,
but Mint base+3rdparty DID grab everything else it / mpg321 needed.
( pardon confusion, 321 vs 123 =  all the same,
if you apt-get or otherwise get "mpg321"
                           you get the "mpg123" command.)

I had it working on CentOS, with full features usable mid-stream,
      ( "h"  would display a menu of commands               like
            " 1,2,3,4,5,6,7,8,9,0" would jump to
                            10,20,.....90% portions of the track)
and so on.           but I dumped CentOS on my fileserver-with-sound,
  replaced with Mint 19.1 (which BTW solved a firefox-hangs-my-box issue)

and I lost the interactive features. e.g. "h" does nothing at the moment,
and when I run mpg123
             I don't see the "type h for help" output I used to get.

So it's just not enabled!

Anyone else use this?   -doug
p.s. whatever Remote Control option is, that's not what the trick needed,
though I don't understand it.  (I stared at the args/Options below until believing I didnt need any of these flags to use the cmds listed )

But what i CAN'T show at the moment is what the interactive cmds
  (which "h" will list, normally) are (were until I upgraded).
But I think i will reboot on the centOS partition and try. -doug
