Grep script that looks for paragraph style A followed by paragraph style B

Question

Hello,
I am fairly new to scripting in Indesign and I have run across something I want to script that I don't know how to do. Two of the paragraph styles that are in our files are Normal and Song. I need to add an extra paragraph return between all instances of Normal followed by a Song. I tried to search the forums to see if this was already on here somewhere and if it is I didn't come across it. I would like to set it up as a grep script but if anyone has an alternative way to do this I would like to know also.
Thanks in advance

Hi,
So you could use a script.
I assume a text frame with proper story is selected and whole story is in one frame or linked frames.
myStory = app.selection[0].parentStory;
if (myStory.constructor.name !== "Story")
     alert ("Select a destination text frame, pls\rand try again");
     exit();
myNormal = app.activeDocument.paragraphStyles.item("Normal");
mySong = app.activeDocument.paragraphStyles.item("Song");
app.findTextPreferences = null;
app.findTextPreferences.appliedParagraphStyle = mySong;
mFound = myStory.findText();
len = mFound.length - 1;
if (len >= 0)
     while (len--)
     currPara = mFound[len].paragraphs[0];
          if (myStory.paragraphs.previousItem(currPara).appliedParagraphStyle == myNormal)
          currPara.insertionPoints[0].contents = "\r";
