Iv heard about a piano cl that teaches u how to play by listening..is that possible?

iv seen an add bfore saying that there is a new way of giving out piano lessons to student which is by teaching the student to listen to the song tht he/she likes..then try to hit the right keys...its weird tho bcs im learning piano myself and i cant seem to see the possibilities in dat...iv had a friend who said its possible as he had tried it before..
