If I Ain’t Got You is a song by US singer Alicia Keys. It came out in 2004. Keys wrote it after Aaliyah, a 22-year-old R&B singer, died in a plane crash (飞机失事) in 2001. This sad news made Keys think about what’s really important. To her, life isn’t about money or fame (名利), but the friendships we make and the love we share.
