I saw a Japanese trailer for Destiny Deoxys where the Dance Mix from the 2BA Master CD was used in the videos final seconds. Have any other America Pokemon songs made cameos in the JPN version?
Also would it be cool if that happen at other times?
M2M's Don't Say You Love Me was considered the American theme song for the first movie, and was played a lot back in 1999/2000 when the fact that Pokemon was internationally popular was made a big deal out of.
The first two movie soundtracks were sold in Japan (popular US music often is). The Japanese Don't Say You Love Me single actually has an exclusive track-the karaoke version of the song.
There was actually an English version of one of the Japanese ending themes, Type Wild. Beyond that, I doubt the US produced music has been used much, if at all, in the Japanese anime or movies.
The English version of Type Wild was produced for the "Pokemon Encore" TV show, which showed reruns of older episodes with both the Japanese and the English audio track available. It's not US music.
Of course, actual US music was used during the English audio track for Pokemon Encore, though.
I think the only instance of dub music actually being used in the Japanese version of the anime is when that awful theme from "The Mastermind of Mirage Pokemon" was used as the opening theme in the Japanese version as well.
