I've been hearing the song umbrella everywhere even if im at the bathroom i can hear somebody humming the song, I searched the net and according to the wikipedia.com there are almost 27 covers and parodies on this music.

few of them where Mcfly, Marié Digby, Taylor Swift , My Chemical Romance, One Republic, Boyce Avenue, Plain White T's and The most fascinating is the cover of Vanilla Sky.

The music was written by Christopher "Tricky" Stewart and Thaddis "Kuk" Harrell and the lyrics and melody were written by Terius "The Dream" Nash with the rap intro written and performed by Jay-Z. The song was produced by Stewart with vocal production by Harrell.

"Umbrella" was not originally written for Rihanna. Christopher "Tricky" Stewart composed the song in 2007, with American pop singer Britney Spears in mind. Her label rejected the song, claiming to have a suitable amount of songs to work with for her future album Blackout, while also Spears having professional difficulties at the time.

The song's reign at number-one in Britain occurred as the UK was hit by extreme rainfall and flooding, which led some people to jokingly suggest the two events were related, the media referring to it as the "Rihanna Curse". Interestingly, the precise day the song was knocked from the #1 position by Timbaland, the weather seemed to improve. A similar situation occurred in New Zealand, where the song hit #1 in the early winter of 2007 as the country was experiencing some of the worst storms in its history.In Greece, "Umbrella" was released at a time when people were suffering through a summer of several major heatwaves topping 47C/117F, and the worst forest fires of modern history, killing 60 people. When the song peaked at #4 in the Greek singles chart in October 2007, the country experienced significant rainfall. Spain also experienced one of its wettest summers in decades, and the coldest August since the beginning of the 20th century during "Umbrella"'s chart run.
