創作背景
Lea於2013年6月初步完成專輯的錄製，這時的專輯裡並沒有Cannonball這首歌。2013年7月，Lea的男友、Glee男主Cory Monteith去世，之後這首歌被加到專輯中，並最終被選作為專輯首單。
Lea在MTV.com
的採訪中曾說，Cannonball這首歌可以說是她失去Cory之後的心理寫照，這首歌鼓舞了她，讓她變得更堅強，幫助她走出Cory去世的陰影。她認為用Cannonball作為專輯的首單十分合適，因為她時常用這首歌激勵自己，她也希望這首歌能幫到更多的人，能在人們遇到困境時給予他們勇氣和力量。

歌曲鑑賞
《滾石》雜誌的樂評者Ron Blistein給這首歌很高的評價，他寫道：“這首歌十分朗朗上口，令人印象深刻，這一方面是由於這首歌的製作者都是經常創造熱單的作者，包括Sia Furler、Benny Blanco等。更重要的是Lea的強大的聲音力量讓這首歌與眾不同，她的聲音在那種百老匯式飈唱和她在Glee中被訓練的流行唱法中轉換自如。 （樂評原文：The track is instantly memorable, not surprising considering the number of top hit-makers behind it, including cowriters Sia Furler and Benny Blanco. Production comes courtesy of the Norwegian duo Stargate. Still, it’s Michele’s powerhouse vocals that take center stage on "Cannonball" as she deftly switches from her Broadway-trained belting and Glee-honed pop chops.）
Digital Spy的樂評者給Cannonball打了三顆半星（五顆星滿分），他寫道：“經常被稱讚為Glee中最好的歌手的Lea Michele又一次證明了自己演唱這種具有強大力量的抒情大歌的能力。而她的個人經歷（指Cory的去世）與歌曲的聯繫使得這首歌更加具有說服力。” （樂評原文：Often lauded as Glee's best singer, Michele has proved time and time again that she knows her way around an enormous power ballad. The fact the star is launching her pop campaign following tragic personal circumstances adds weight to her debut single's conviction.）
歌曲MV
Lea在Cannonball MV中Lea分兩階段完成MV的錄製，分別在2013年的11月和12月。MV是由
Robert Hales導演、Estee Stanley設計的。Stanley在採訪中曾這樣解釋這支MV的創意：“我們不希望這支MV有太過花哨的場景和服裝，我們希望突出Lea她本人和音樂。”
這支MV於2014年1月9日在Lea的VEVO官方頻道首播。截至2014年6月4日，已經有近一千萬的播放量。
