The 'Lust for Life' singer discussed his memories of his late friend - who died of cancer in January - and had a special playlist that spanned the 'Ziggy Stardust' hitmaker's career on his two-hour BBC 6 Music show 'Iggy Confidential'.
And Iggy admitted he had personally chosen the songs according to his memories of Bowie.
He said: ''The way I chose them was from memory.
''I took out a piece of paper and a pen and closed my eyes and just remembered what I liked at different times ... I'm weighing things that are a little more low on the totem pole, but not obscure.''
Before he played 'Wild Is the Wind' from 'Station to Station', Iggy recalled all the ''strange'' people who were hanging out at the recording studio when Bowie was working on the track.
He said: ''This was recorded at Cherokee Studios, which was just a very typical, good old solid rock'n'roll studio owned by some guy who was connected to some guy who always had a mountain of drugs. And there were people with hair too long for their bodies coming and going in weird cars. And strange girlfriends.''
Iggy also shared anecdotes about eating burgers with Bowie and Frank Zappa, the room that inspired the ''blue, blue, electric blue/ that's the colour of my room'' line from 'Sound and Vision' and the recording process of 'Low'.
After the 'Sorrow' singer died in January, Iggy remembered him as the ''light of [his] life''.
He tweeted: ''David's friendship was the light of my life. I never met such a brilliant person. He was the best there is.''
Bowie and Iggy toured together in 1976, before sharing a home in Berlin in 1977, where the 'Aladdin Sane' hitmaker helped his pal write his first two post-Stooges solo albums, 'The Idiot' and 'Lust For Life'.
Iggy's live shows at that time saw his friend join him on keyboard, while he provided backing vocals on Bowie's seminal 'Low' LP.
