Short description of Virtual Music Composer 4.0: Musical tastes as personal preferences are mostly too subjective. As such they are different from each other. With regards to the subject matter, the estimation of a program efficiency is not a question about anyone's musical taste. All that counts is the amount of time you spend on listening to. Virtual Music Composer works on the basis "Just listen to the music". There's no doubt that everyone's favorite song comes soon or later.
