Batch and/or Repeat Function

Hello. New to this forum. I imported 300+ .mp3 files from an IPOD, and would like to change their filenames from the Itunes "ABCD" format to the title of the .mp3. I can accomplish this with 5 separate steps on each file, but I hope someone will suggest a batch or repeat function to use. Thank you.

I should have searched a little more. I found Pol Davril's response to a similar request in March, modified it to fit my requirement, et voila!. Mission accomplished. Thanks.
