We love the '90s: Kimbra is the first woman born in the '90s to top the Hot 100.

'LIGHTS' UP: In its 19th week on the Hot 100, Ellie Goulding's "Lights" shines in the chart's top 40 at last. The song rises 49-40, aided by a 32-28 lift on Digital Songs and a No. 69 debut on Radio Songs. In its eighth week on Pop Songs, it pushes 24-22.

The steady ascent of "Lights" to the Hot 100's top 40 is the third-longest by a woman in one chart run. Here is a look at the songs by female artists to take the most scenic routes to the region over one release cycle:

Weeks to Top 40, Title, Artist (Peak Pos.)
24 weeks, "Don't Know Why," Norah Jones (No. 30)
23 weeks, "Suddenly I See," KT Tunstall (No. 21)

19, weeks, "Lights," Ellie Goulding (No. 40 to date)
19 weeks, "La Tortura," Shakira featuring Alejandro Sanz (No. 23)

Including songs by women that have spent more time climbing to the top 40 over two releases, LeAnn Rimes' "Can't Fight the Moonlight" (2002) required 29 weeks to crash the barrier. The song remains tied with 2 Unlimited's "Get Ready for This" for the longest journey to the Hot 100's top 40, the latter track having done so in one chart run.

BIG RASCALS: A lead single from a studio album reaching No. 1 on the Country Songs chart has become a lock for Rascal Flatts, as "Banjo," which rises 3-1, becomes the trio's fifth consecutive such song to lead the list.

Here is a recap of Rascal Flatts' last five sets, all of which have yielded No. 1 first singles on Country Songs:

2012, "Banjo," from "Changed"
2010, "Why Wait," from "Nothing Like This"
2009, "Here Comes Goodbye," from "Unstoppable"
2007, "Take Me There," from "Still Feels Good"
2006, "What Hurts the Most," from "Me and My Gang"

All five collections have likewise topped Country Albums, bringing the act's total to seven leaders on the ranking. "Banjo" is the band's 12th Country Songs No. 1 dating to its first, "These Days," which began a three-week rule the week of Nov. 30, 2002. Rascal Flatts is tied with Carrie Underwood for the third-most toppers in that span, trailing only Kenny Chesney (16) and Brad Paisley (15).

OFFSPRING ON: The Offspring bows at No. 31 on Rock Songs and Alternative Songs with "Days Go By," the title cut to the band's ninth studio album, due June 26.

The song marks the group's 25th entry on the latter list dating to its first, the two-week No. 1 "Come Out and Play (Keep 'Em Separated)," in 1994.

Earlier this year, the group premiered the Offspring: Rock Prodigy app for iPad, iPhone and iPod Touch users. The app serves as a personal music teacher, presenting a note-for-note song tutorial and including tips directly from band members Dexter Holland and Noodles.

"Finally, my kids can learn my tunes," Noodles said upon the app's release. "They might actually think I'm cool."
