The easiest way to do this is to not think in terms of 10 tracks.
Find the cheapest and smallest memory solid state mp3 player money can
buy and buy 10 of them. Have them running all the time and use a wafer
switch to select the headphone out. clamp the play button pushed so
that it will play when it is powered up and replace the battery with a
power supply wall wart.
If you have to have buttons to activate a track then cut the front
panel with a ravor blade around the play button and use epoxy
conductive adhesive to build your connectors for the play button.
If you want it to work using only one player then you will have to
find a player with a remote control to cut up and you may then wish to
be cd player based. The hard part doing this is that to play track one
often you will have to activate two buttons (1 then enter) which takes
a little more creative electronics to work for you.
Please report back what you find as the easiest way.
