The music box


Compilations
disc_changer_small First compilations
the record changer -
a pile of singles records on your automatic radiogram: to change the order, remove the discs, shuffle and reload
juke-box-wurlitzer-small First programmed and play list: the juke box -
big, bulky and superb:
put coin in, choose B3, D2, F6and let the machine play.
recorder Early compilation system:
the reel to reel tape recorder -
later models became fantastic music making machines with stereo and even quadraphonic tracks.  
K7-walkman The personal cassette player: the Walkman started it all.
easy to use, cheap and cheerful,
but music was sequential and
tracks difficult to access.
discman-sony330 Personal CD player: 
the Discman: CDs on the move;
can jump to any track, can play a programme, or at random and repeat tracks,etc. A bit bulky.
ipod video black Personal MP3 player:
Compilation + playlist + miniaturize the device, like the famous iPod.
All modern mobile phones are also MP3 players.
Remember: all the music files are stored on the player; loose the player, you loose all the music.
