ActionScript 3.0 :: Dynamic Textfield Masking With Non-dynamic Mask?

I'm creating a playlist for a music player, and I've got the song names displaying correctly in my songTitle holder MC, but there's limited space for the song names to be shown in, and I'm going to eventually have it inside a scrolling movieclip. Problem is, the text inside the textfields disappear when I try to add a mask to the movieclip they're being loaded into. I've tried adding all combos of embedFonts, antialias, and blendModes I ran into, to no avail.how to mask dynamically created textfields with a non-dynamic (Flash IDE-made) mask.

Code:

for (var i:int = 1; i <= _size; i++) {
var pl_artist:TextField = new TextField;
//all embedFont = true and antiAlias commands no workie
}
