They do their best to appeal to younger voters by regularly shunning suited formality, using slang and showing off their knowledge of popular culture.
One Labour MP said Led Zeppelin II simply 'blew me away'
But it seems the musical tastes of Britain's politicians are stuck mostly in the 1970s.
When asked by the British Library to name their favourite number one album, rock veteran's Led Zeppelin's 1969 classic Led Zeppelin II came out top.
Albums by The Beatles, Pink Floyd and Deep Purple were also popular.
According to Tory shadow immigration minister Damian Green, Led Zeppelin II is "the ultimate album for teenage boys - metal as art. No-one ever topped it. The opening riff is straightforward perfection".
Lib Dem MP Lembit Opik said: "Zeppelin made a new kind of music. They created a genre many have copied but no-one has equalled. And Whole Lotta Love is the greatest rock song ever."
Labour's Alison Seabeck added: "Led Zeppelin simply blew me away."
However, for Culture Secretary Tessa Jowell it was The Beatles' Sgt Pepper's Lonely Hearts Club Band.
Education Secretary Alan Johnson preferred the band's Revolver, along with Labour colleague Peter Kilfoyle. Ex-Conservative leader Michael Howard went for The White Album instead.
Respect MP George Galloway chose Blood On The Tracks by Bob Dylan, while Labour's Rosemary McKenna picked the Saturday Night Fever soundtrack.
"It's a fantastic dance album and never fails to make me smile," she said. "It's the most played on my iPod and in my car."
Lib Dem MP Mark Oaten singled out Human League's 1980s classic Dare. "This album reminds me of my last year at school and brings up a lot of happy memories. Every track is a killer, not a filler," he said.
The Manic Street Preachers' This Is My Truth Tell Me Yours was Northern Ireland Secretary Peter Hain's choice.
Lib Dem Jo Swinson, who at 26 is the Commons' youngest MP, went for Oasis' (What's The Story) Morning Glory, while Schools Minister Jim Knight and Labour colleague Ian Pearson selected Pulp's Different Class.
David Bowie, Elvis, Blondie, U2, Frank Sinatra, Marvin Gaye and Lionel Richie also made it on to the list.
Tory Mark Field said Swing Out Sister's It's Better to Travel was his favourite, commenting: "It brings back wonderful memories of my undergraduate days in the mid-to-late 1980s. It still brings me out in goose pimples and smiles."
Every album that has reached number one can be heard at listening stations in the entrance to the British Library from Friday.
