Default [Q] Iconset/XML Question

I'm working on a widget that will use the Media Utilities Current App variable (TMU_CURR_APP) to set an icon for that app. I'm fairly certain the problem is happening when I try to test for the value of #TMU_CURR_APP#. Is there a different operand I need to use to compare string values?

Thanks!

Code:
<config>
    
  <title>MU Current App Icon</title>
    
  <description>Media Utilities Current Application Playing</description>
  
 
  <demo>music.png</demo>
  
  
  <icons>icons</icons>

  
  <default>music.png</default>
  

  <condition>

	<test>#TMU_CURR_APP#="Google Play Music"</test>
	<image>playmusic.png</image>

  </condition>

  <condition>

	<test>#TMU_CURR_APP#="BeyondPod"</test>
	<image>rss.png</image>

  </condition>	

  <condition>

	<test>#TMU_CURR_APP#="Spotify"</test>
	<image>spotify.png</image>

  </condition>
