Gordon Brown, Nick Clegg and David Cameron picked All My Loving, A Day In The Life and The Long And Winding Road respectively
It's fair to say that what you listen to, can reveal a lot about what you're like.
So what does the Prime Minister's choice for his favourite Beatles track say about him?
Gordon Brown's picked All My Loving.
Politicians were asked to choose their top track by the Fab Four as part of Liverpool's Beatles Day Celebration, which take place on 10 July.
The PM said choosing his was tough: "It is so hard to pick one because there are so many but this was my early favourite because it was the first I learnt to play on the piano when my parents sent me for lessons when I was young."
Tory leader David Cameron's plumped for The Long And Winding Road.
Cameron, who admits he's a McCartney fan, says the song sums up his life as leader of the opposition.
Liberal Democrat leader Nick Clegg opted for the Sergeant Pepper hit A Day In The Life.
He explained why he picked it: "The dramatic shift of gears musically leading to the powerful piano chords at the end are frighteningly effective, while the lyrics are incredibly effective by combining the mundane everyday life with the tragic death of someone in a car crash."
There's a strange fascination in knowing what music makes our politicians tick.
It can give us an insight into what they're really like, but sometimes it can get embarrassing.
While he was still Chancellor Gordon Brown said he liked listening to the Arctic Monkeys.
But, his fan credentials were questioned when he couldn't actually name a single album track.
Gordon Brown says the Arctic Monkeys are good to wake up to
It led to accusations he was jumping on the bandwagon.
Was this a desperate attempt to look cool?
In an interview with Newsbeat in 2006, the PM told Newsbeat it had all been taken out of proportion.
He said: "What I said was the Arctic Monkeys would wake you up in the morning because of the noise.
"I have got the album actually because I've heard it and listened to it."
The PM told us he prefers to listen to the Beatles and is also a fan of Coldplay, because bassist Guy Berryman is from his home town Kirkcaldy.
Aside from Chris Martin's dulcet tones, it seems that the PM also likes a bit of Saturday Night Fever.
In an interview Robin Gibb claimed the Prime Minister played their songs "every day", adding: "Gordon likes our music and I like him."
While we're rooting through politician's MP3 players, Tory leader David Cameron is a Killers fan who also likes to listen to The Smiths, Blur, Bob Dylan and Radiohead.
Lib Dem leader Nick Clegg says his favourite album is Changes by David Bowie.
Democratic US Presidential hopeful Barack Obama has Jay-Z and Stevie Wonder on his playlist.
