itunes plays music from middle

when i play songs in itunes it plays it from a random place. so it may start playing at 1 minute 30.

I remember i turned this feature on a few weeks ago, but now i want to turn it off but i've forgotten how i done it. I can't find out how to turn it off anywhere.

does anyone know how to turn it off?

uhh i think if you go on song info ( +i) you can chooose where the song starts and ends. The only problem i can think of is if you have a large libary it could take forever!

Oh thanks so much, I've got 791 songs which comes to 3.82 gb. it only took a 2-3 seconds for it to do the whole library....
