Zero Freitas has been obsessed with music since he was a little boy growing up in Brazil.
Since buying his first record as a teenager, he has steadily built up a collection of vinyl to rival any in the world.
Now in his 60s, Freitas owns more than 5 million records, thanks largely to his fortune built operating a bus company in Sao Paulo.
He buys discs from all over the world and employs a team to process and catalogue them.
Now, in an interview with BBC News, Freitas has explained that the records are to be catalogued with a view to creating a searchable – and listenable – collection.
