I love the Challenger!! and Smile full versions. They sound even better than the TV sized versions, and Challenger!! happens to be my favourite opening. As for Pokémon Ieru Ka Na 2004, and Pokéfuri Game no Uta, they were disappointing. I mean, why couldn't they of made an Ieru Ka Na with the Hoenn Pokémon? And where is Imakuni? And why is Pokéfuri Game no Uta such a lame song -- thirty seconds of singing, and three minutes of the same beat played over and over.
Oh well, Challenger!! and Smile make up for the rest of the CD.
