Crooner Robin Thicke is back with a smashing hit, Pretty Lil' Heart, featuring familiar friend Lil Wayne. The single is from Robin's upcoming fifth album, Love After War, which should be release around 6 December. In an interview with Rap-Up, Thicke described the recording process as "coming great." "I think you get to that point where you hate it and then you love it. It's like any important relationship in your life," Thicke said. "Just myself, written and produced, like the first few albums." It seems the 34-year-old singer-songwriter is really heading back to his sound from The Evolution Of Robin Thicke days. Pretty Lil’ Heart has a classic old-school soul sound with a smooth hip-hop edge and Wayne serves a slick verse in the intro.
