Rockers Paramore have scored their first number one album in America. The group, fronted by colourful Hayley Williams, leads a string of debuts to the Billboard 200 top 10 with its new self-titled release, which bows at number one with 106,000 first-week sales. The album just pipped Brad Paisley's Wheelhouse to the top spot by 6,000 sales. Paisley's new release is his fourth successive number two debut on the countdown, tying Sheryl Crow for the most number twos without a chart-topper. Meanwhile, Justin Timberlake's former number one, The 20/20 Experience, slides to number three and Blake Shelton's Based on a True Story holds onto the number four spot. Eric Church's Caught in the Act: Live debuts at five. Other new entries in the top 10 are Tyga, who bows at seven with Hotel California; rockers Volbeat, who debut Outlaw Gentlemen & Shady Ladies at number nine, and Stone Sour, who return to the top 10 at 10 with House of Gold & Bones, Pt. 2. Meanwhile, Pink returns to the top of the singles chart with her fourth number one. Just Give Me a Reason rises from three to one on the Hot 100, leapfrogging Macklemore & Ryan Lewis' Thrift Shop, which stays put at two, while last week's chat-topper, Bruno Mars' When I Was Your Man slides to three. South Korean pop star Psy is making another charge for the top of the charts with his follow up to Gangnam Style - his Gentleman debuts at number 12 on the countdown, thanks to 27,000 downloads since its release online on Friday (12Apr13). The video for the song has already been viewed by more than 125 million people worldwide on YouTube.com.
