You are on the right track.  Combine the two and you would likely have
eventually got it:

#!/bin/bash
find /home/mmay3/Music/tori_amos -iname '*.mp3' -type f |
while read FILE
do
  mv -v "$FILE" `echo $FILE | tr ' ' '_' | tr '[A-Z]' '[a-z]'`
done

Changes:

1) used a while loop instead of a for loop
2) corrected the syntax of the find
3) placed quotes around $FILE

I would have made two more changes to yield this mv command:

  mv "$FILE" "$(echo $FILE | tr ' A-Z' '_a-z')"

1) uses $() instead of backticks ``
2) collapses the two tr commands into one

Your logic was sound, just your syntax needed a little tweaking.
