Find and gather a Boombox tape in the world.
The boombox is a portable music device, that can be bought in the Awesome Shop. Some music tapes can also be purchased in the shop - but for this achievement you need to discover one tape by exploring out in the world.
There are three (known) available to find, and you only have to get one - but they are not listed in the interactive map linked elsewhere in this guide.
The Satisfactory fandom wiki describes where they are.
