So what's the right way to do this? I hacked one together the other
day:

IFS=$'\t\n'; for i in `find . -iname \*m4a`; do faad... blah blah blah

and I knew it was a hack because setting $IFS just seems
bad... possible unintended consquences, but it worked.

I have seen something like the following:

find | while read FILE;
        do echo "$FILE"
done

  2.  In all cases, the idiom used is:

         ifs=$IFS
         IFS='....' # whatever you need for your particular problem.
         ...        # your code
         IFS=$ifs
         ...        # any other processing that needs to be done

I missed the original postings (on vacation;). But, regarding IFS, a couple of notes: 1. In "The UNIX Programming Environment", Kernighan and Pike, this variable is used without any caveats, in several of the example scripts. This guarantees that the original value, whatever it is, is restored and used for "normal" processing.
