Desert Island Discs is a long-running show on BBC Radio 4 which asks each guest a straightforward question: if you were trapped on a tropical paradise, which eight records would you want to listen to? Microsoft co-founder and philanthropist Bill Gates will soon be sharing his selections when a special episode airs on January 31st. The songs will be complimented with a "rare personal interview" conducted by Kirsty Young, which will explore not just the music but also the moments, people and events that Gates remembers through them. So, any guesses for what would be on his perfect playlist? A little Weezer? Maybe some U2?
