I am so glad that I stuck through and decided to watch "Prince of Tennis" and all of their OVAs even though I already read the manga and know what will happen. Not only did I get to see the little chibi episode (which was funny as hell), I also got to listen to all the amazing music they use for openings and endings. After a little research, I found out that the voice actors of the anime worked together to create different bands to sing songs for the anime. In one of the fan DVDs, they did a marathon of 100 songs by the characters and bands they created. I absolutely love their voices! Especially, Kikumaru Eiji (Hiroki Takahashi has an amazing voice range! Look him up on youtube and you'll understand what I mean!) and Shiraishi Kuranosuke's (that Osaka dialect is just pure sexy in my opinion) voice. Anyways, I'll stop my rambling and get on with the few songs that I found awesome:
Wonderful Days (7th ending)- Pulltab to Can (Band formed by characters: Atobe Keigo, Kirihara Ayaka, Sengoku Kiyosumi, Sanada Genichirou, Kamio Akira, Ibu Shinji, and Ooshitari Yuushi)
Little Sky (8th ending)- Kentaro Fukushi
Hello& Goodbye (Nationals Arc OVA 1st Ending)- Kondou Kaoru
These next two are songs that the characters did and is not from the anime. Both of them are a play on the old and famous Japanese fishermen song "Soran Bushi". I think the lyrics are funny. Especially Shitenhouji which had many interesting characters lol.
Kiku-chan no Soran Bushi- Kikumaru Eiji
Naniwa no Soran Bushi- Everyone from Shitenhouji
