Vibe believed that there would be no "all-black female R&B group having a chemistry, cultural and commercial impact as remotely comparable as TLC" and dubbed CrazySexyCool as "the blueprint for female ensembles to follow". The Philippine Daily Inquirer called TLC "the most influential female group the world has ever seen". Singer Beyonce, the former lead singer of Destiny's Child stated that "TLC has influenced just about every female group that's out there now, and they definitely influenced Destiny's Child." Craig JC from Clutch wrote that TLC were "big and influential" during the 1990s, and that their contemporaries such as SWV, Total, Blaque, 3LW, Brownstone, 702, Jade, Xscape and En Vogue did not have TLC's crossover appeal." David A. Keeps from Rolling Stone explained the impact of TLC:  TLC's career has been filled with both hits and headlines. The group was one of the few R&B acts to build a strong identity out of its initial success, and they exerted more control over each successive record. Their music - particularly the 11-million-selling CrazySexyCool and the 6-million-selling FanMail, both of which won two Grammys each - set the standard for contemporary R&B. TLC helped to pioneer a deft blend of acoustic and computer sounds that paved the way for groups like Destiny's Child, as did their image as independent women. Whether addressing AIDS in "Waterfalls" or the struggle for female self-esteem in "Unpretty", they showed themselves able to take serious issues to the top of the pop charts.  TLC is the best-selling American girl group of all time with 65 million records sold worldwide. According to the Recording Industry Association of America (RIAA), TLC is the best-selling female singing group in American music history, with 22 million certified albums. CrazySexyCool remains the only album by a female singing group to receive the RIAA diamond award. According to Billboard, TLC is the second most successful girl group of all time on the Billboard charts, behind only The Supremes.
