Montage Riddles

What is This Fruit?
Riddle:
I am a fruit. If you had two of me, I would sound just the same. If you rearrange my letters, it could be a crime. Add me to a montage and I can become a different fruit. Remove my head and you can still listen; take away the end and I can still be eaten. Without a piece of the center, I am still a word; take away all of the middle and I am just an acronym. What am I?
