Because of how awesome it would be to have songs from the Portal 2 OST(s). I listened to different mixes and recordings, and I have concluded that it would be freaking amazing to have! We are in need of more electronic chip tune stuff, and it would be just so perfect.
"Science Is Fun"
"The Friendly Faith Plate"
"I Saw A Deer Today"
"Four Part Plan"
"Want You Gone" (Jonathan Coulton)
...and possibly medleys of the other songs!
Make this happen RBN!!!!
