I want to play my songs out of an older version of itunes but when i try opening a song with the older version it says "file cant be opend because it has been created by a newer version of itunes." I want to use the older version because when i used to play toribash and listen to music the frame rate would only drop to 45 or something which was tolerable but with the new version of itunes when i play music and play toribash the frame rate drops to like 20 or something which is not playable. So is there a way to play songs out of my older version of itunes? Also i have a mac.

As people obviously cant read worth anything let me make this very clear.
I have a mac. Because I have a mac suggesting things that are only for windows does not help me whatsoever.
