Currently available as a free download on the European PlayStation Store, the PlayStation 20th Anniversary theme for the PS4, PS3 and Vita adds a little PSone to the sound mix.
The PlayStation is 20 years old today, and while startup and menu music has come along way in two decades, there's just something about that alien-sounding PSone startup tone that just gets a person ready for some gaming. YouTuber Ray Palafox II (via PlayStation LifeStyle) captured the tone on video for those of us in North America, who will hopefully be getting the theme when the store updates later today.
Once this is on my system, all I'll need is one of those snazzy 20th Anniversary PlayStation 4 consoles and I'll be in celebratory business.
Update: It's now available in the North American PlayStation Store.
