I know that there was a German soundtrack that had completely different songs to the US version, so that might account for a song like "Racing Heart" which I've never heard of and is not on my DVD. Also, sometimes they change the music when it's being shown on TV (look at all the different versions for "Sixteen Candles", for example.) However, the songs listed here on imdb are the same songs on my DVD copy.
1. i finally found a copy of 'racing heart' by melanie safka which was used for the pool scene in the german version. http://www.youtube.com/watch?v=OnLJxJcPGGE obviously, this was on german tv. :D
2. i've had a look at the us version. with regard to music, yes, it is totally different.
