1. I have added more songs' origins to the first post. Feel free to check it out
2. Thanks everyone for support and contribution. Be careful not to repeat songs that someone already posted
3. I have spent hours of wiki-ing, googl-ing, youtub-ing, listening and comparing, double checking and triple checking JUST TO MAKE SURE that those origins are TRUE ORIGINS. This is a tough and time-consuming work so I am progressing very slowly
4. I am still figuring out an efficient way to manage the (potentially) huge list of songs and their respective origins. I need answers to the following questions:
a. Do I need to categorize the songs? If so, by which category? Genre? Difficulty?
b. Do I need to sort the songs? If so, in which order? Alphabetical one? By Genre? By Difficulty?
c. How to search for songs efficiently in this list if it goes to multiple pages in this thread (I hope it will though lol)? Ctrl-F surely fails if there are too many pages.
