The Disc Manager

A guy has gone for exploration, and he discovered an extinct lost civilisation inside a cave. Where he found out they used to live in a place that looks like dungeons and strongholds. And he also found out about their obsession with music, and they used to make music and store it on discs. So he was trying to find all the discs they made and found some discs, and he’s making a collection of them. He's naming the discs based on how the music sounds or how the discs look like or other hints he found around the discs.
