Coffin with built-in speakers linked to a music playlist.

A coffin with built-in speakers linked to a music playlist that can be updated by the living has been designed in Sweden.

The hi-fi coffin designer, Fredrik Hjelmquist told reporters that the coffin is engineered as an entertainment medium for the dead and provide solace for grieving friends and relatives by making it possible for them to alter the deceased’s playlist online.

He planned to be buried in such a coffin and would choose opera for his long sleep. He has not sold any of his coffins, but there have been many enquiries, he said.

The coffin goes for 199 000 Swedish crowns ($30 700).

“We’ve had an unbelievable amount of inquiries, not so much in Sweden, but many from the United States and Canada, also from Taiwan,” he said.

Somebody ought to do it because this is really rock n’ roll I think...but at the same time beautiful,” he added.
