Building the world's biggest record collection
16 March 2015 Last updated at 00:06 GMT
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.
Zero's ultimate ambition is to create a vinyl library accessible to the whole world.
BBC News went to meet Zero Freitas and find out why he was driven to collect records.
