Mary J. Blige keeps the goods coming ahead of the December 2nd release of The London Sessions LP with “Not Loving You” co-written by UK phenom Sam Smith. The track is a tender power-ballad packed with piano chords and the sentiments of a heavy heart. The bittersweet lyrics find Mary J. urging her partner to practice self-love with an emotionally-wrought vocal that conveys the urgency of her words and owns the entire track. Check out the clip below to listen to “Not Loving You.” Pre-order The London Sessions via iTunes. Stay tuned for more from MJB.
