Get pressed into a vinyl record
So you never wrote a top-40 hit in this lifetime. That's OK, because you can become one in the next. For 3,000 euros, And Vinyly will press your ashes into a 12-minute vinyl record. You can choose to play music, a vocal message ("I'm spinning... from BEYOOOND THE GRAVE!"), or nothing at all. Just be forewarned that if there's copyright infringement on your dead-body record, you're on your own. But hey, you're dead. So who cares?
