An inventor has used the philosophy that "music can be good for your soul" to create his very own coffin that is complete with a built-in stereo.
The CataCombo Sound System, which costs around 18,500 pounds, is aimed at music-lovers who don't want to rest in peace.
Customers can compile their own personal playlists before they die and the music will be streamed into their coffin.
Even when they have gone, relatives can update the songs for their dearly departed via Spotify and a "Catatomb app" using a touch screen built into the gravestone.
The music is piped into the casket by two-way front speakers, 4in mid-bass drivers, divine tweeters and a hell-of-an-8-inch subwoofer.
They are all powered by a custom 2.1 amp and fine-tuned to the coffin's unique interior acoustic space which is fitted with an external cooling system so they don't overheat.
The whole system is also completely soundproofed so that it doesn't wake the dead lying nearby.
"Just because you are dead, you should not be deprived of the life-enhancing power of music," the Daily Mail quoted inventor Fredrik Hjelmquist as saying.
"Some people believe that a beautiful melody can reach beyond our senses. Now you can expect nothing less than godlike comfort and heavenly sound from the catacoffin.
"This is designed to allow customers to embrace their passion for music, in this life and the next. Hi-fi is my biggest passion in life, and I will take it to the grave.
"People in Sweden are so stuck up about death - I wanted to give them something to laugh about. I was very afraid of death and I wanted to lighten it up a bit," he said.
So far, the 48-year-old from of Stockholm, Sweden, has only invented his own personal musical coffin, but he is ready to take orders for others as well.
