After no solo male artists had begun their discographies with a pair of No. 1 entries on Billboard's Pop Songs radio airplay chart between its inception in 1992 and last year, two such singers have achieved the feat this year.

Taio Cruz becomes just the second male soloist to top Pop Songs with his first two charted tracks, as "Dynamite" ascends 2-1. The British singer/songwriter/producer spent three weeks at No. 1 with his debut single "Break Your Heart," featuring Ludacris, beginning in May.

Cruz joins Jason Derulo, whose "Whatcha Say" began a four-week reign on the Nielsen BDS-based Pop Songs tally in November. His "In My Head" followed with a two-week rule beginning in April. Derulo is aiming for an unprecedented third consecutive career-opening leader on Pop Songs with "Ridin' Solo," which bullets at No. 7 for a fifth consecutive week.

"Break Your Heart" and "Dynamite" appear on Cruz's debut album, "Rokstarr," which opened at its No. 8 peak to-date on the Billboard 200 in June.

Even arriving with one introductory No. 1 on Pop Songs is a rare feat. Prior to Derulo and Cruz, nine solo males had reached the pinnacle in their first visits to the chart: Shawn Mullins ("Lullaby," 1998), Eagle Eye Cherry ("Save Tonight," 1998), Ricky Martin ("Livin' La Vida Loca," 1999), Lou Bega ("Mambo No. 5 (A Little Bit Of ...)," 2000), Gavin DeGraw ("I Don't Want to Be," 2005), Chris Brown ("Run It!," 2005), Ne-Yo ("So Sick," 2006), Flo Rida ("Low," 2008) and Jay Sean ("Down," featuring Lil Wayne, 2009).

Billboard's Pop Songs chart, along with all surveys on billboard.com, will be refreshed Thursday (Aug. 26).
