Barack Obama has already proved that he's likely the US President with the hippest taste in music. Way back in 2008, when the Illinois senator was running for the presidency and doing his utmost to connect with a younger generation, Obama waxed lyrical about his iPod playlist to The Guardian which contained everything from Bruce Springsteen to Bob Dylan to Ludacris to Stevie Wonder.

Well, in keeping with his respect for musical pioneers, Obama has written a letter to the family of legendary DJ Frankie Knuckles who passed away earlier this month. Knuckles was seen as a pioneer of the golden age of house music in the 80's and was a big figure in Chicago, where Obama and his wife Michelle spent the majority of the late 80's and 90's.

DJ David Morales uploaded the letter to his social media pages from Knuckles' memorial service.
