If you didn't know, I will change all of my songs names, ending with ([insert roman number here (ex: Chocnoon - Oxymoron (CLI))]).
What if you reach 4,000 songs?
Simply, I can put like for example, (IV*XI), IV*XI is basically like 4,006 in roman numerals.
And 4 million?
I can put two asterisks, for example: (IV**XL) if I get the 4,000,040th song. Obviously, that's not gonna happen though, and also because an average Colombian man lives about 77 years, and I post about 4-8 songs a week (usually 5-7 because of school).
You may already know that.
I - 1
V - 5
X - 10
L - 50
C - 100
D - 500
M - 1000
Use * if big number (Ex: MMMDCLI*CMXIX, which is 3651919).
