Hi Ron.

I got a little curious about the subject when I read your post.
If there is no information in the file in the form of tags or text that can be seen by Cakewalk or other programs such as GN-Midi, MidiPlayer 6 etc., it seems there are a number of apps that can recognize melodies.
Did a Google search, there even came up an app that can recognize songs by singing, whistling or using 'humming'. surprised

Never tried any such apps myself, but used this search string at Google just to see what came up:
"how to recognize song titles and artists by playing a melody"
