For a long time I’ve felt super-ripped off by the mobile phone market. I worked as a sound editor/recordist and composer for years and to see people paying top dollar for ring tones that are ridiculously easy to make (and even worse back before polyphonic entered the scene) and using awful sound quality is enough to destroy the morale of any musician or sound professional. I’ve just come around to the other side. I sold my first ring tone at
