Need help with MSXML2.serverXMLHTTP request

[Ski2004_2005]

Hi. I think I'm close and have googled until the cows come home. I need to return a "p class" value from a series of websites. My code currently reads:
-----------------------------------------
Dim getArtist As Object
Dim getSong As Object
Set xmHtml = New HTMLDocument
With CreateObject("MSXML2.serverXMLHTTP")
.Open "GET", URL, False
.send
xmHtml.body.innerHTML = .responseText
End With
Set getArtist = xmHtml.getElementById("onair-pdt").getElementsByTagName("p")(0)
MsgBox (getArtist.innerText)
Set getSong = xmHtml.getElementById("onair-pdt").getElementsByTagName("p")(1)
MsgBox (getSong.innerText)
--------------------------------------

I have also tried WINHTTP.WinHTTPRequest.5.1. I can return the values by opening Internet Explorer and navigating to the page but it takes far too long for what I need to do. The main difference is I can refer to the getElementsByClassName when opening Internet Explorer but can't with MSXML2.

The HTML for this example is shown below. What I need is the innertext values of p class "onair-pdt-artist" and "onair-pdt-song":

-------------------------------------------------------------------
div id="on-the-air-content" style="display: block;">
div class="module-content theme-color-content-bg clearfix">

div id="onair-pdt" style="display: block;">

p class="onair-pdt-artist">Chainsmokers/Coldplay

p class="onair-pdt-song">Something Just Like This

--------------------------------------------------------

Thanks in advance.
