Function Get-MetaData() {
	Param (
		[string]$folder = "C:\Users\Public\Music\Sample Music")
	
	# To Do...really need to push to PSObject and not just to a temp hash value...
	
	ForEach($sFolder in $folder) {
		$a = 0
		$objShell = New-Object -ComObject Shell.Application
		$objFolder = $objShell.namespace($sFolder)

		ForEach ($strFileName in $objFolder.Items()) {
			For ($a ; $a  -le 266; $a++) {
				If($objFolder.getDetailsOf($strFileName, $a)) {
					$hash += @{ `
						$($objFolder.getDetailsOf($objFolder.Items, $a))  =`

					}
					$hash
					$hash.Clear()
