The audio keeps looping from 0.00 til 01.28 seconds although the full song is 2.00 mins.

I just uploaded an audio song to aftereffects and it's 2.00 minutes long, but when I play the audio it keeps looping the first 1.28 seconds of the song why?

After Effects is not an NLE. It was never designed to edit video. You use AE to create effects shots and short motion graphics sequences that you cannot create in an editing system. You have probably just run out of system resources with your current frame rate, frame size,
