<p>A caller tune, also known as a ringback tone or welcome tune, is a personalized audio or music clip that is played to a caller instead of the traditional ringing sound. Caller tunes have become increasingly popular as a way for individuals to express their personality, interests, or even promote a business or product.<br />
