Leehom debuted the first song "What's Up Rock!!" (搖滾怎麼了!!) on radio in September 2008 . This song shows a fusion of his "chinked-out" style with the genre of rock involved as well. He collaborated with Janet Hsieh playing the Pipa, merging traditional Chinese sounds with that of modern electric guitar to unveil rock with an Eastern touch.
With the release of the song, Leehom announced his MUSIC-MAN World Tour, which kicked off at Taipei Arena as a prelude to his album . In his concert, he debuted three new songs: "Dirty Love" (愛得得體), "No Reason to Pay Attention to You" (我完全沒有任何理由理你) and "Everything". However, the title track of the album, "Heartbeat" (心跳) was not introduced until December 8, when the song was released on the radio.
