High Frequencies warping in iTunes?!

Wow you guys, I have never had this problem before and I hope someone out there can help me.

I just mixed and mastered a song on Ableton.

I play the wav. file, it’s fine.

I play the wav. or mp3. file in iTunes or my iPod and all high frequencies sound like there is a strong phaser on them. All the high hats are dragged out and warped.

I mastered the song multiple different ways and nothing works, it seems it’s just Apple stuff.

None of the other tracks I’ve done sound like this… so what’s going on?!

Can someone please tell me how to fix it?
