Wave was announced as CNBLUE's third studio album on August 5, 2014, with a release date of September 17. Describing a wave as having various shapes of "top, middle, and bottom", the title is meant to represent varying songs included on the album. Frontman Jung Yong-hwa explained that the band wanted "people who hear our songs to feel our music like they ride a wave", while also desiring "our music to spread" on a global scale. Due to the band's constant travels, the members wrote songs while on the road. Guitarist Lee Jong-hyun wrote "How Awesome" on a mobile app during an airplane flight, while "Control" was conceived by Jung in a hotel in Japan. While staying at a hotel during the band's Arena Tour 2013: One More Time in Japan, the bassist Lee Jung-shin wanted to write a song. Jung assigned him and the drummer Kang Min-hyuk to do it together; after listening to the melody of "Control", they conceived the idea of writing a love song, which Jung rejected. After discussing it between themselves, Kang and Lee agreed to write a song with the notion that "no one can control me". Initially written in Korean, the two faced difficulties in translating the song into English. With Jung's assistance, the translations and lyrics were completed; Kang and Lee were left uncredited. The song was originally intended to be included on the band's mini-album Can't Stop released in South Korea, but was ultimately excluded. Jung cited the limited space on the release, as well as the "different atmosphere" the song had in comparison to the other songs for its omission. He decided to add it onto the band's single "Go Your Way".
Music structure
A rock album, CNBLUE incorporates electronic dance music into the record. In addition to noting that the latter was a tend at the time, Jung expressed the view that the two genres were similar in terms of their rhythm and different in instrumentation. In utilizing both genres, he felt that the two "fit to each other". He described the album as "clear, fresh, and refreshing". The opening track is an introduction, which the band omitted on its previous album What Turns You On?. The bassist Lee felt that it was needed in order to "understand the atmosphere of the album". The track begins with a guitar riff before a melody is introduced. This is followed by "Radio", a "danceable" rock track where the band integrates "strong electro sounds" into the song. Recorded with various instruments, clapping, and chanting, "Foxy" is a song that deals with the "admiration of a sexy woman". "Truth", "Lonely Night", and "Still" were identified as the few songs which dealt with the subject of love. Guitarist Lee described "How Awesome" as an expression of "the relationship of our fans and us".

The first single to precede Wave was "Truth", which was released on April 23, 2014. In addition to the title track, a music video for the coupling song "Still" was also made available.

The track was used as the opening theme song for the music show Music Launcher, and as the closing theme song for Music BB and Rokemitsu Friday.
