Katy Perry does double duty at No. 1 this week on both the Billboard 200 albums chart and the Digital Songs tally thanks to the arrival of her “Teenage Dream” album.

Her second Capitol effort starts atop the Billboard 200 with 192,000 according to Nielsen SoundScan — marking her best sales week and a new chart high. She’s the first solo woman to reign at No. 1 since January, when Ke$ha’s “Animal” spent one week atop the list.

Over on the Digital Songs chart, “Teenage Dream’s” title track moves up one spot to spend its first frame at No. 1 with 259,000 (up 24%).

Perry’s last album, 2008′s “One of the Boys,” debuted and peaked at No. 9 in July of that year with 47,000 sold in its premiere week. Its best sales frame came over Christmas week of 2008 when it shifted 63,000 — but at a lower rung on the tally.

On Digital Songs, “Teenage Dream” gives Perry her second No. 1 of the year. She earlier reigned for five weeks with the album’s first single, “California Gurls.” The latter is on the verge of becoming the year’s top selling download with 2.6 million sold. Its sum falls just shy of 2010′s best-seller: Train’s “Hey, Soul Sister” (3.8 million).
