Jay-Z and Beyonce, who reportedly wed on Friday (April 4), join a list of married music power couples that include Jennifer Lopez and Marc Anthony, Nas and Kelis, and Faith Hill and Tim McGraw, pairs that have seen their nuptuals impact their mutual record sales.

Beyonce and Jay-Z tying the knot has been a major news story, but if the tepid blog buzz is any indication, the event will likely exert little or no change over the pair's sales. According to data from Nielsen BuzzMetrics, which measures blog trends, while blog traffic about the couple and about Beyonce individually rose 375% and 200% respectively, Jay-Z individually saw a bump of less than one percent.

Several other music husband-and-wife teams that preceded the long-dating Jay-Z and Beyonce to the altar have seen mixed post-marriage sales numbers.

Jennifer Lopez and Marc Anthony both saw a decrease in album sales after they exchanged vows on June 5, 2004. Prior to their union, Lopez released three albums, which have sold a combined 8.1 million in the United States, according to Nielsen Soundscan.

Lopez's post-wedding 2005 album, "Rebirth," has sold 731,000 copies, while a pair of 2007 albums, "Como Ama Una Mujer" and "Brave," fell to 200,000 and 154,000, respectively.

Anthony released seven albums between 1994 and early 2004, with combined sales of 2.5 million. His biggest selling album to date is his 2002 crossover set "Mended," which has moved 680,000 units. His first post-wedding album, "Sigo Siendo Yo," released in 2006, has moved 151,000 copies to date, while his 2007 album, "El Cantante," has sold 183,000.

Nas and Kelis have also seen a sales decline since their Jan. 8, 2005, wedding. Nas' eight pre-marriage releases have sold a combined 11.3 million copies, while Kelis' two albums released before 2005 add up to 785,000. Post marriage, Nas has sold 755,000 of 2006's "Hip Hop Is Dead," while Kelis has moved 157,000 with "Kelis Was Here," released in 2006 as well.

In comparison, Faith Hill and Tim McGraw, whose joint tour was the 8th highest grossing tour of 2007, have seen steady sales, and in some areas even a boost since they married on October 6, 1996.

Hill's two albums released prior to marrying McGraw have sold a combined 3.6 million. McGraw's three pre-marriage albums have sold 9.3 million.

Still, while McGraw's biggest selling album is his 1994 release, "Not a Moment Too Soon," with 6 million copies sold, Hill's top seller is "Breathe," with 6.5 million copies, which was released three years after her marriage to McGraw.

Like Hill and McGraw, Beyonce and Jay-Z have achieved success working together. The pair have collaborated on the songs "03 Bonnie and Clyde," which reached No. 4 on the Billboard Hot 100 and No. 5 on Hot R&B/Hip-Hop Songs, and "Crazy in Love," which topped both charts.
