ADELE - New Song (snippet)
 

Popular singer-songwriter ADELE has just teased a new song in the X Factor ad breaks even though it never mentioned her by name. Lyrics were on screen though. Early speculation (from me) would suggest it could be about her estranged father. It's very beautiful judging by the admittedly very short snippet.
