It's been a long journey． From DJ to producer to singer, Mark Ronson is now a pop star in his own right．

On Feb 15, his hit song Uptown Funk won Record of the Year, one of the most important prizes, at the 2016 Grammy Awards．

While the world has gone crazy for the song, Ronson, 40, went through six difficult months to produce it． In fact, the UK musician made 17 versions (版本) of Uptown, Funk．

In an interview with the Daily Mail, Ronson told the UK newspaper that he worked so hard that his hair started to fall out． At one point, the stress of trying to come up with a suitable guitar part even caused him to f'aint (晕倒) in a restaurant．

The difficulties didn't stop there． Ronson also didn't have enough confidence in his singing, as he had been a producer for a long time． "I work with great singers," he told the New York Post, "so I've always heard what really good voices sound like． "

Still, things worked out great in the end．

His family plays an important part in his success． His stepfather guitarist Mick Jones was one of the first members of the rock band Foreigner and faometimes Jones would share ideas with Ronson．

"After school, Jones would play me the most recent mix of songs in the studio and ask what I thought, and l would tell him in my little English schoolboy voice, 'I remember the bass (贝司) was turned up a little more on the mix from last week''', Ronson told The Guardian, "I was kind of meant to live in the studio． "

All these influences led to his success． Ronson taught himself how to DJ when he was 16． "I practiced by copying my favorite DJs on the radio," he told US radio station NPR． "I would listen to them and try and copy in my best way what they were doing． "

With the goal of being a cool DJ, Ronson dropped out of New York University and played in clubs in downtown New York, where popular artists often visited．

"If you do a good job, there's the chance they might remember who you are," he told NPR．

And doing a good job is how Ronson got into show business．

" Never underestimate (低估) Ronson," UK DJ Zane Lowe told Esquire magazine, " he is fu]ly prepared for opportunities． "
