Well, besides being funny the obvious draw to this OVA is hearing our favourite characters sing.
1. Heart Nibun no Naisho (Live Version) - Secrets of the Heart Split in Two - Akane Song
2. Little★Date (TV Service Version) Ranma, Akane, Shampoo cover of OP2
3. Musabetsu Kakutou Itchokusen ~Panda Wa Uta Wo Utaenai - The Direct Path of Anything Goes Martial Arts ~Pandas Can't Sing - Genma Song
4. Wo De Ai Ren - My Lover - Shampoo Song
5. Niji to RINKU no BARAADO ~Itoshi no FURORENSU - Rainbow and Rink Ballad ~Darling Florence - Azusa and Mikado Song (very nice treat, not usually available for Azusa/Mikado fans)
6. Kawaiku nee, Iroke ga nee - You Ain't Cute, You've Got No Appeal - Ranma Song
7. Mori e Ikimashou - Let's Go to the Forest - Kodachi's rendition of Polish Folk Song
8. CHAINA Kara no Tegami - Letter from China - Ranma & Ranma-chan (girl-type Ranma) Song
9. Yume no Balloon - Dream Balloons - Ranma-chan (girl-type Ranma) Song
10. Akane no Komoriuta - Akane's Lullaby - Akane Song
I find myself particularly drawn to this anime for nostalgia purposes of a time where it was popular among anime to showcase your cast in a singing competition - my other favourite example being "Magical Girl Gigi."
This is an OVA for those who enjoy a good talent show.
