Hello shippou5, to Windows 7 Forums,
#1. Open Start/All Programs/Maintenance/Problem Reports and Solutions.
In the Problem Reports and Solutions window,
Click Change settings, Advanced settings and
Turn off problem settings. A program/app not closing properly, I would certainly want to know how to correct it.
#2. You can add a playlist as a folder to the Music Libraries or just make a new Library as shown in the link provided; How to Create A New Library In Windows 7 « My Digital Life
Hope this helps
