(After Effects) Change text content over the time - text

Question

I would like to put the title + artist name when the song is playing, but I don't know how to achieve this, because with almost 30-35 songs, it would be long and boring to create a specific text layer for each song.
If there is a trick to achieve this quickly.

Answer 1

You can achieve this via scripting.
I have these two scripts that should do what you want. I wrote them some time ago. Maybe you need to do some adjustments.
This one adds several text layers from a csv file.

This one should add one text layer with the source text set to the content of a csv.
https://github.com/fabiantheblind/after-effects-script-snippets/blob/master/text_to_comp.jsx
This is a minimal example to add a text layer with sourceText
/**
* main function
*/
var main = function() {
var txt = ['Hello - World', 'dog -cat', 'foo - bah']; // the text to add
app.beginUndoGroup('add source text'); // open a undo group
var curComp = app.project.activeItem; // get the current comp
// check if the curent active item is a comp
if (!curComp || !(curComp instanceof CompItem)) {
alert('noComp');
return;
// end if no comp is active
}
var txtLayer = curComp.layers.addText('titles'); // add a text layer
var counter = 0; // the time to add a keyframe to (in seconds)
// loop the text
for (var i = 0; i < txt.length; i++) {
var curFrame = (counter / curComp.frameRate); // calc time for each frame
$.writeln(curFrame);
// add a keyframe with the text as value every frame
txtLayer.text.sourceText.setValueAtTime(curFrame, txt[i]);
counter++; // increase the time by one
}
app.endUndoGroup();
};
main();
