Playlist creator for mp3s and wma's

Question

I wrote the following pretty quickly this morning to traverse a directory and it's child directories to look for any mp3/wma files in that directory and make a windows media m3u playlist (basically, the file names separated by newlines).
I thought I'd post it if anyone needs it or if anyone can find something I'm overlooking. It seems to work correctly, but it's hardly tested well.

I have also Paid this morning, approximately 3-4 hours ago, and cannot play from my phone, or play ad free on my mac.
This quite frankly pisses me off and this is unacceptable. I paid money for your service which doesn't even work. Sooo give me a free month or fix your problems. I don't pay your company money for **bleep** that doesnt work.
I've recevied my Receipt of payment already, and it's processed through my bank account. This does not make me very happy at all.
