Miley Cyrus' "Breakout" (Hollywood) and Sugarland's "Love on the Inside" (Mercury Nashville) continue their charge towards the No. 1 slot on next week's Billboard 200 albums chart, as the two sets still lead Nielsen SoundScan's Building chart, released today, July 25.

Unweighted sales of "Breakout" through the close of business Thursday, July 24 stood at 205,000, ahead of "Love on the Inside's" not-far-behind tally of 189,000.

Billboard estimates the nine merchants who report to Nielsen SoundScan's Building chart -- Trans World Entertainment, Best Buy, Circuit City, iTunes, Starbucks, Borders, Target, Anderson Merchandisers and Handleman Co. -- comprise about 80% of all U.S. album sales.

This is the first time since December that the No. 1 and No. 2 albums on a Friday Building Chart have each chalked up more than 180,000. The last time it happened was the week before Christmas, on the Dec. 21 Building Chart, when Josh Groban's "Noel" (143/Reprise/Warner Bros.) and Mary J. Blige's "Growing Pains" (Matriarch/Geffen/IGA) were No. 1 and No. 2.

Final figures for this sales week -- which ends on Sunday, July 27 – will be announced on Wednesday, July 30.
