Washington, Feb 10 : John Mayer has revealed that till date he feels bad about his 2005 `Song of the Year' Grammy Award - because he believes fellow nominee Alicia Keys was the real winner.

The singer/songwriter, who was honoured with Best Male Pop Vocal Performance gong at the 51st Grammy Awards ceremony, held on February 8, 2009, for his hit `Say', has admitted that he didn''t feel his `Daughters' track should have won gold four years ago.

"I''m still enough of a music lover to know when people get it right and when people get it wrong. Every once in a while I''ll get a Grammy and I''ll go, ''Yeah, I really thought that was a special moment that I had on tape,'' but then other times I think other people should win it," Contactmusic quoted him, as saying.

"I won Song of The Year for a song called Daughters... and Alicia Keys, who I love so much, was up against me with a song called If I Ain''t Got You and she played at the Grammys, and I was like, ''This is the most amazing thing in the world.''

"I won and I didn''t think I should because she had a better song," he added.

The win haunted Mayer for years - until he got the chance to work with Keys and give her part of his Grammy trophy.

"She came over to my apartment and I said, ''There''s something I''ve gotta give you,'' and I took the Song of The Year Grammy and, with my brute, semi-drunk strength, removed the top half of the Grammy and gave it to her," he said. (ANI)
