Music files help

I need some help with some music files i have on my pc.
I can listen to them properly through media player ,but when i try to open them with itunes they go into itunes but its like they play on fast speed.
Need some help in getting them into itunes properly.
Can anyone offer some advice.

Try getting Info and slow down the speed.

As for me, I need help making songs unlicenced. Got anything for that?
