Morning Glow was a preloaded ringtone on the Sony Ericsson K750, the popular camera phone released in 2005. On some other Sony Ericsson models the same tone was listed as Purple Sunrise, which is why both names circulate online. Like many mid-2000s polyphonic ringtones, it was preserved by enthusiasts who ripped phone sounds for archives and remix culture. Today it survives mainly as a nostalgia trigger, shorthand for early mobile era mornings and a quick retro alarm in short-form video.
