Despite the clichéd "My" prefix and the axiomatic poor acting I honestly can't work out if I like or hate "MySong".
Given that the songs originally contained some passion / enthusiasm all the program has to do is match notes and play the MIDI.. but at the same time the simplicity of the program (and particularly the "mood" settings) do seem like something one would struggle to easily do.
Maybe Ruth (or anyone with real musical skill) will be able to make more comments on this.
