*TLC’s new greatest hits album “20” is set to stomp into the top 20 of the Billboard 200 chart next week.

Industry sources say the set might sell around 15,000 to 20,000 copies by the end of the tracking week on Sunday, Oct. 27, reports Billboard. That could represent at least a 200 percent gain over last week’s sales, when it debuted at No. 72 with 5,000 sold, according to Nielsen SoundScan.

The gain was triggered by VH1’s premiere of its biopic “CrazySexyCool: The TLC Story” on Oct. 21. Its bow scored nearly 4.5 million viewers, according to Nielsen, making it VH1’s highest-rated original movie ever.

According to VH1, “CrazySexyCool” is also the No. 1 original cable movie of the year among adults and women 18-49.

“20” was released on Tuesday, Oct. 15, and features 13 previously-released hits, along with one new song, “Meant to Be.” The act was last in the top 20 with 2002’s “3D” album, which debuted and peaked at No. 6 on the Nov. 30, 2012 chart.
