First of all, unless you wrote the program to read from the (remapped) serial port, and enabled time-stamping output from the player, the "sleep" program wouldn't be able to know when new songs started playing. Secondly, there is no way yet to start another program from within the player; you'd have to start it running before the player started, meaning there'd be no way the program would know when to start counting.
