Learn how to sing soul and blues from the heart. Listen to and imitate singers like Martha Reeve, Dusty Springfield and Aretha Franklin. Take that style and fuse it with a modern, world-weary attitude.
Sing lyrics about heartbreak, cheating and sexy shoes. Turn the art of rock lyric writing into poetry with songs like "Wake Up Alone" and "Me and Mr. Jones." Show a propensity for emotional warbling and lyrics that belie your age.
Draw from your real-life experiences to write powerful songs like "Rehab." Record the diatribe against being forced into alcohol and drug rehabilitation and turn it into your most famous and lauded song.
Use your distinctive stage presence to further accentuate the power of your songs. Wear your jet-black hair in an updo, draw on cat-eyes and wear vampy high heels.
Meld the low, smoky tones of a jazz chanteuse with some of the lesser known girl group vocalists of the 1960s. Emphasize this combination to get your vocal sound on songs like "Me and Mr. Jones."
