Custom Audio: Ending music sync issues.

I know that currently through the ui you cannot set these tracks but i was curious so i did it through modifying a preset and most of the ending music is out of sync, seems to be due to the ending sequences running too fast? this includes the music when zelda sends link back in time, and all of the credits music although, the track when link is walking out of the temple of time is not nearly as bad but it is still delayed. This was done with my enhanced ost mod which uses streamed audio.
