Your hearing of her pronunciation is correct, the words of her song were:
If you want it, take it. I shoulda said it before.
Tried to hide it, fake it. I can't pretend anymore.
But her pronunciation matched "try to" the way that American English speakers actually pronounce the words, almost as one word, try-da. Unfortunately it is very similar to the way that we pronounce "tried to," tryd-da.
However, "Try to" also works here perfectly well. When I listened to the song, I actually heard, "Try to" rather than "Tried to," and I'm a native English speaker. I scrounged all over the internet looking for an official copy of the lyrics to make sure.
Speaking clearly the difference between the two would be fairly obvious and the "d t" would be significantly different sounds. In rapid conversation or in singing, those hard t's quickly become softer d's and it all blends together.
