[MKANET]

I haven't had much time to cleanup my script. But, I did want to post what I do have. It was quick and dirty; not, intended for public (so sorry for it's current condition). As soon as I get a chance, I'll update this post again with less overly-complex code. My script wouldn't even be useable if it wasn't for Glenn. As always, thanks Glenn.

Code:

set-executionpolicy bypass
$currentlyPlayingArtist = $NULL
$logfile = "C:\Users\MKANET\Desktop\invalid-urls.log"
if ($logfile){del $logfile -ErrorAction SilentlyContinue}

$artistFolders = dir ([environment]::getfolderpath("MyMusic")) -Attributes Directory -Exclude "*My Music*"
$MusicDirPath = ([environment]::getfolderpath("MyMusic"))

#Music Directory Path Override:
#$MusicDirPath = "$($PSScriptRoot)\Fanart"
