Hey You

麦当娜为07年环保LIVE写的歌曲。

　　"Hey You" is a pop charity song by American singer-songwriter Madonna. It was co-written and co-produced by Pharrell. The song was released as part of the Live Earth campaign and was free to download from websites like MSN. It was released digitally as well as on the CD and DVD of the Live Earth concerts on December 4, 2007. Musically it is a stripped down, folky ballad with straight-forward, anthem like lyrics talking about how to save the world from destruction. The song received mixed reviews with one group of reviewers commenting that the modest message of the song was uninspiring while others called the song sweet and commended Madonna's commitment to charity.

　　Released initially as a free download for a period of seven days and not receiving any promotion at all, the song performed poorly in most the countries. It entered the charts of countries like Canada, Sweden and Switzerland but failed to cross the top forty in their charts. Madonna only performed the song once in the Live Earth concert, London where she was joined by a choir of school children who provided backing vocals to her singing while the backdrops displayed images relevant to the song's message, like natural devastations, different cultures and political leaders.
