Melanie Fiona’s over six week run on the R&B/Hip Hop Songs chart has officially come to an end thanks to smooth crooner, Robin Thicke. Late last week Thicke’s single “Sex Therapy,” from the album of the same name, rocketed to the top of the chart. A follow up to hits including “Magic” and “Can You Believe,” “Sex Therapy” is Thicke’s second single to top the chart. It follows the 2007 breakthrough single “Lost Without You”. Thicke’s success wraps up what ended up being a several week strong hold for Grammy nominee Melanie Fiona. Fiona’s Juno Award nominated “It Kills Me” had reigned atop the R&B/Hip Hop Songs tally for a total of seven weeks.
