Avatar: The Last Airbender
A soundtrack CD, "The Legend of Korra: Original Music from Book One", was released on July 16, 2013. It features 26 instrumental tracks. Konietzko wrote that the album release required "an incredibly frustrating wait and battle" to overcome "a bureaucratic impasse". He wished for the record to be commercially successful to convince Nickelodeon to release an "Avatar: The Last Airbender" soundtrack, a subject of many fan petitions. The day after its release, the album was the bestselling soundtrack album and no. 5 in the pop sales rankings at the online retailer Amazon.com.
