Now I want to rename these files, which are all lectures to have the date of creation/lastmodified in the file name.

Your file name has a space in it, so the command you ran is: "mv" "Voice" "036.m4a" "Voice 036.m4a-2015-05-07 06:51:59.000000000 -0400" And since "mv" got 3 arguments, it requires that the last one is a directory. If you had quoted "$file" after mv, it should have worked properly.
