Because despite of what most people say he is really talented and broke the strings when he was in Take That to do what he wanted to do and succeed and so far has gone on to become one of the biggest popstars ever, and so far the best selling British male with over 55 million albums and 17 million singles worldwide. According to the United World Chart, he is the most successful male from 1997 to 2007 and the third artist overall behind Madonna and Britney Spears. He so far has won more Brit and Echo Awards than any other artist in history and made it to The Guinness Book of World Records when 1.6 million tickets were sold in a single day shortly after he announced his World Tour in 2006. Apart from the success, his albums are like stories telling the story of his life whilst is still easy for the listeners to relate to the songs in many ways.
I've liked Robbie since he started his solo career, i remember buying his first two albums and all, but i wasn't really a fan until he released his third album "Sing When You're Winning" in 2000, that's when i really became a Robbie Williams fan, so that makes it seven years.
"No Regrets" - it is my favourite song ever by any artist, for personal reasons this song is really a song that describes just the way i feel about a lot of things i've been through in my short life - and the album where it was taken from, "I've Been Expecting You" is my favourite album too.
