“Back To Black” by @amywinehouse has officially joined the @YouTubeMusic #BillionViewsClub 🎶👏 After the release of her debut album, ‘Frank,’ Amy turned to girl groups and sounds of the 60s for inspiration for new music. According to @rollingstone, Winehouse explained that she had “been listening to ’60s bands and girl groups and it came out in the writing on ‘Back to Black,’” and even cited The Velvelettes and the The Shangri-Las as two of the groups who influenced her writing.
