DISCLAIMER! I am NOT responsible for any damage to your phone, loss of data, use of your phone, or spontaneous sharknadoes that may occur if you try these steps! It worked for me, but I make no guarantees that it will work for you! Back up all your data and your ROM, and use this at your own risk!
These instructions work to recover any deleted files whether they are Music, Photos or even Apps after Rom Install Wipe or even Factory Reset.
These instructions even work to recover any type of data after accidental delete.
I tested myself after Installing CM10 on my sisters SGSII and she told me afterwards that all her photos, all 1200 of them, yes 1200!! were gone!! I of course immediately asked her why the hell did she save the photos to the internal memory instead of the SD Card

12) Check "Enable Deep Scan" if the first time you did steps files were corrupted. Sometimes this helps recover them.

Explaining this is too complicated for Noobs so don't worry about it.
