Open a blank document in your TextEdit app.
Go to the Format menu, and click "Make Plain Text" (don't miss this step)
Now, open your folder (the one with a thousand songs)
Select all the songs (Command-A will do that)
Press Command-C (places file names on clipboard, which is a copy)
click in the TextEdit window, and press Command-V (to paste the names)
And - voila!
All your song titles in a list....
