A CD player takes in electrical energy (electrons) and energizes its circuitry.  Some of these electrons are used to induce a laser, thus releasing electrical energy as light.  The laser is used to "read" the bumps and crevices on a spinning disc, and transcribe the light into sound.  The sound is amplified by other circuitry that includes an earphone or speaker so the sound can be perceived.  The spinning disc gets its motion from a motor, which also uses electrical energy to rotate. So light, sound and motion from one device!
