Waiting Music Instead of Ring Tones

It greatly disturbs me that some people value individualism over respectful conformity now to the point to where they modify their phones to force their favorite pop song in the ear of the person calling them instead of the traditional ring. No matter if its their grandmother, a businessman, or a someone mourning over a tragic event looking to be consoled, they are forced to listen to a crappy upbeat pop song when calling this person - this seeker of extreme individuality. It's rude, inconsiderate, and egotistical...it grinds my gears.
