I don't know what you're trying to say because your sentences have no real subject.
But uh, is this what you're talking about?
No, I mean a program that replaces the MP3s in the MP3 Folder and keeps track of what the new MP3 you just copied in was named/titled.
So, Say, you use it to replace Trust In Your Force with.... Never Gonna Give You Up.
You open the program. It brings up a window with boxes. One box has 2 columns, the other box has your MP3 Library.
In the 2-column box, the left column has the names of the MP3s in the MP3 Folder (Boss.mp3, Field_XX.MP#, etc.) OR details about the mp3(Boss Music, Tir Chonail Theme, Ferghus Theme) and the other side has what it was named when the program was used to copy it in. (RainbowRock.mp3, Rock_Lobster.mp3, HurricaneDial.mp3).
So, in the 2-column box, you click the track for the Rundal Boss Music, and in the library box, you click your rickroll song, click a "Replace" button and BAM! You set yourself up to get trolled while fighting a Cyclops, and, so you don't forget, the new Right-column in the 2 column box now says "Rick Roll", which is what you titled that MP3.
There. Is that more clear?
Also, thank you for pointing me to that jukebox.
It's going to be so helpful as I manually change out MP3s
