Bubble Trip/Sweet Sweet Song

"Bubble Trip / Sweet Sweet Song" is the sixth single by Japanese singer Anna Tsuchiya. It was released on 1 August 2007 by Mad Pray Records, an imprint of Avex Trax, as a double A-side single. The release pairs the rock- and R&B-influenced "Bubble Trip" with the pop rock track "Sweet Sweet Song".

The single was issued in two formats: a regular CD edition and a limited CD+DVD edition containing the music video for "Bubble Trip". Both songs were later included on Tsuchiya's album Nudy Show!.

Following the single "Lucy", "Bubble Trip / Sweet Sweet Song" continued Tsuchiya's mid-2000s run of rock-oriented material. Issued on 1 August 2007, it was promoted as a double A-side and released through Mad Pray, Tsuchiya's Avex imprint.

Like many Japanese singles of the period, it was tied to several commercial campaigns. "Bubble Trip" was used as the Herbal Essences Japan television commercial (CM) song, while "Sweet Sweet Song" served as a Premium DAM karaoke CM track for the Daiichikosho company.

"Bubble Trip" is described as a blend of R&B and rock, built around a rhythmic groove and electric guitars. The song was written by Negin, Siam Kamli, Brian Kierulf and Josh Schwartz, with production handled by KNS Productions, who had previously contributed to material on Britney Spears' third and fourth studio albums.

"Sweet Sweet Song" is a more straightforward J-pop/pop rock song, composed and arranged by Ayumi Miyazaki, with lyrics credited to Tsuchiya under her pen name ANNA. Together, the two tracks highlight the contrast between Tsuchiya's glossy, Western-influenced sound and her more traditional pop-rock songwriting aimed at karaoke and live performance.
