Question: "These Are the Times" is the second single released from the second album of Dru Hill, an American singing group, most popular when?
Context: Return of Dragon is the second studio album by American R&B recording artist Sisqó of Dru Hill, released on June 19, 2001 on Def Soul Records.  The album did very well on the charts but its singles, "Can I Live" and "Dance for Me", were commercial disappointments compared to his debut album, "Unleash the Dragon" (1999).  Despite the fact that Sisqó announced a third single, "Dream", this never materialized due to the commercial failure of the album.  The song "Without You" was originally planned to be featured on Dru Hill's third album, "Dru World Order" but tensions grew between the group while working on the album and it was put on hold.  "Return of Dragon" was later certified Platinum by the Recording Industry Association of America (RIAA) for excess of one million copies.  "Return of Dragon" would be Sisqó's last album until "Last Dragon" (2015). "In My Bed" is a number-one platinum-selling R&B single by R&B group Dru Hill.  It is the second single from their eponymous debut album.  The single spent three weeks at number-one on the US R&B chart and peaked at number four on the US pop chart.  The song is performed by group leader Mark "Sisqó" Andrews.  The music video focuses on Sisqó's girlfriend, who cheats on him with another man and the other members of the group, but Sisqó doesn't know anything about it.  At the end of the video, Sisqó goes to his house with a bouquet of flowers for his girlfriend when he sees a guy walking out.  He goes inside and sadly finds her in bed with a woman and drops the flowers in heartbreak.  He leaves the house for a few seconds and goes back in.  The remix features Jermaine Dupri, who also produced the track, and Da Brat.  It was a hit single.  The remix sampled Le Pamplemousse's "Gimme What You Got" (1976). "These Are the Times" is the second single released from Dru Hill's second album, "Enter the Dru".  The single reached number 21 on the Hot 100 and number 5 on the R&B chart, staying on the chart for 21 weeks.  The music video directed by Bille Woodruff was inspired by the film "The Man in the Iron Mask".  Sisqó played both the good twin and the evil twin and Jazz, Woody and Nokio played the Musketeers.  Actress Lark Voorhies appears in the video as Sisqó's love interest. Dru World Order is the third studio album by American R&B group Dru Hill, released in late 2002 (see 2002 in music) on Def Jam Recordings' Def Soul imprint.  Four years had passed between this release and the group's previous album, "Enter the Dru", during which time the quartet imploded, yet later reformed.  Beginning with this release, Dru Hill became a quintet, with fifth member Scola (Rufus Waller) added to the original lineup of Sisqó, Jazz, Nokio, and Woody.  This was the first and only time that Dru Hill was featured as five members.  The album released three singles "I Should Be...", "I Love You" and "No Doubt".  Two of the singles had music videos released.  This is the group's last album for the entire Def Jam roster and they were released from their contract within a year due to poor album sales for this album and Sisqó's second album, which caused the group to go on a second hiatus. Enter the Dru is the second studio album from American R&B group Dru Hill, released October 27, 1998 on Island Records.  The album's name comes from Bruce Lee's film, "Enter the Dragon".  This is the first album that the group were credited as executive producers as all four members wrote and produced several of the songs.  It released three singles "How Deep Is Your Love", "These Are the Times" and "You Are Everything".  The singles all had music videos released, but the music video for "You Are Everything" was a remix video, which featured rapper Ja Rule, and Woody did not appear in it due to his exit from the group in early 1999.  The remix version was featured on lead singer Sisqó's debut album, "Unleash the Dragon".  Recording sessions for the album took place at Larabee Studios in Los Angeles, California.  The album peaked at number two on the "Billboard" 200 chart.  On May 1999, It was certified double-platinum in sales by the Recording Industry Association of America (RIAA), after sales exceeding 2,000,000 copies in the United States.
