CTD when adding custom sounds

[tschutschi]

Hi there

 

So for a dungeon mod I'm working on I want to add some custom sounds.

It is kinda a fun mod and I'd like to have the following music to play when you're facing the final boss:

Now I managed to find a way to place a sound in my dungeon.

However when I enter the cell with my sound the game crashes.

 

If I replace that file with a random vanilla sound, it works fine.

I uploaded both files here: https://mega.co.nz/#!uUlVUTRA!deYNIXM1NdWnSmvFkZBeuGOvNE1AVNLA27bKgbprWtQ

what is so different with both these files that one crashes and the other doesn't (except for the filesize)?

 

thx in advance for any help :)
