Stockholm firm Pause Ljud & Bild said its CataCombo Sound System coffins have two-way speakers so the living can hear the music that's playing inside the coffin and a headstone with a digital display to tell visitors the name of the current track, WNYW-TV, New York, reported Wednesday.
The package costs a total $30,000.
The company said its first customer, Fredrik Hjelmquist, is allowing strangers to add tracks to his "Pause 4-ever" playlist.
