Assuming you are using Mp3tag, the button could look like this:

@nodeselect 
"/programfilesx86/Mp3tag/Mp3tag.exe" /fp:{filepath}
Button as XML 
<?xml version="1.0"?>
<button backcol="none" display="both" label_pos="right" textcol="none">
	<label>Mp3tag</label>
	<icon1>/programfilesx86/Mp3tag/Mp3tag.exe,0</icon1>
	<function type="normal">
		<instruction>@nodeselect </instruction>
		<instruction>&quot;/programfilesx86/Mp3tag/Mp3tag.exe&quot; /fp:{filepath}</instruction>
	</function>
</button>
