It's no secret that Robin Thicke is trying his hardest to win back his estranged wife, Paula Patton. But it seems as if his publicity campaign for the album may have backlashed, as preliminary numbers for the first week sales for his new album 'Paula' are a disappointment in comparison to how well 2013's 'Blurred Lines' album sold.

U.K.'s The Guardian reports that since its release on July 1, 'Paula' only sold 25,000 copies in the U.S. according to Billboard, and only 530 copies in all of the U.K. 'Paula' was number 9 on the Billboard 200 in the U.S., while it barely squeaked in at number 200 in the U.K.

To put things in perspective, 'Blurred Lines' sold 177,000 copies during its first week in U.S. and debuted at No. 1 on the Billboard 200.

At the end of March, Thicke and Patton announced that they were splitting amidst cheating gossip. But Thicke quickly made his intentions clear, as he wrote and performed his new single 'Get Her Back' at the Billboard Music Awards, named the album after her and dedicated 'Forever Love' to her during the BET Awards.

The album 'Paula' also features several heartfelt songs that are either dedicated to Patton, or winning love back in general, such as 'Love Can Grow Back,' 'Still Madly Crazy' and 'Too Little Too Late.'

'Paula' is clearly an album that Thicke feels is personal to him and his relationship, but without an upbeat track like 'Blurred Lines,' he may have difficulty finding an audience that is looking for emotional heartbreaking music amidst a sea of fun, positive summer tunes.
