Thrilling! Is this love?

Thrilling! Is this love? (ドキッ ! こういうのが恋なの？) (also stylized as Thrilling! Is This Love? in Lyrics Card 1) is the song used in Fan Club and Fan Club 2 in Rhythm Heaven and Rhythm Heaven Megamix. The song was written and composed by TSUNKU, arranged by Koichi Yuwasa, performed by Eri~na from Canary Club in Japanese, Lorea Ferris Dandoy in English, Jessy Roussel in French, Mai Hahne in German, Costanza Rufo in Italian, Vanessa Cebrian in Spanish and an unknown singer in Korean.

The song was released as part of Canary Club's 2nd album ② Ee ja Nai ka (②エエジャナイカ) on August 26, 2009 in Japan.

The song was performed live during a promotional concert for Rhythm Heaven, where the audience was asked to take part in the song. It was also performed live in Rhythm Tengoku: The Uta Matsuri+, once to show the new singer Ari~sa (this version being used for Fan Club in the game) and a second time to show the "New Arrange Version", arranged by Kaoru Okubo, which was used in Fan Club 2 in Rhythm Heaven Megamix.

While Ari~sa's performance replaced the original in Japanese, the other languages kept their original recordings. The "New Arrange Version" was also edited in a lower key outside of the Japanese version to match the original arrangement.
