Through this album, he promoted the issue of global warming and raised environmental awareness. The packaging of the album used only recycled paper and contained no plastic. He believed that small changes by each person can change the world. "To change the world, you start with changing yourself." Reviews of the album were generally positive, defining the album as "mature." An online album poll organized by China's Sohu, however, suggested that Wang's album did not meet expectations. Netizens remarked that his chinked-out productions were more impressive, although that genre itself has also been criticized. Nonetheless, over 1 million units were shipped on the first day of release. The album broke past 2 million sales, becoming one of Wang's best-selling albums. In August 2008, Wang sought US$320,000 in damages for plagiarism by Pritam, an Indian composer. The lead song for the movie "Race" (2008), composed by Pritam, was allegedly copied from "In the Depths of the Bamboo Forest," a single taken off from Wang Leehom's "Shangri-La" album. In November 2008, Wang was selected to conduct the Hong Kong Philharmonic Orchestra for their 2008 annual grand finale, being the first Asian pop musician to conduct the orchestra. The concert "Hong Kong Music, Leehom Wang" (港樂‧王力宏) was held in the Hong Kong Cultural Centre for three nights, with four shows, receiving CNN International coverage throughout. Wang embarked on his second world tour, the MUSIC-MAN Tour, in the latter months of 2008. The tour commenced with two shows per night in the Taipei Dome in September 2008, three months before the release of Wang's thirteenth studio album, "Heart Beat". "Heart Beat" was released on December 26, debuting at No. 3 on the weekly G-Music charts. The album peaked at No. 1 on its seventh week of release, ultimately staying on the charts for 17 weeks. Like Wang's previous album, "Heart Beat" showed a similar emphasis of rock influences. The album largely focused on guitar and electric guitar solos, which Wang also used for performances in most of the album's music videos. Wanting to continue a similar "chinked-out" element, the album's first single, "What's Up with Rock?!" incorporated rock influences with Chinese flavor. For the track, he worked with pipa artist Liu Fang, and the two concentrated on mixing both electric guitar elements and pipa strings into the song.
