The latest batch of downloadable songs for Rock Band Unplugged for the PSP includes the stirring love anthem "Still Alive" from Portal, which will be available, free of charge and includes delicious cake.

I almost missed the inclusion of Jonathan Coulton's masterpiece in the list of new songs coming to the Rock Band Unplugged Music Store next week, mainly because they tucked it further down the list after the Dixie Chicks "Sin Wagon". My eyes read "Dixie Chicks" and tend to wander off. Luckily for us all I soldiered on, reading about the coming of The Pixies' "Here Comes Your Man", R.E.M.'s "Losing My Religion", and "Pride and Joy" from Stevie Ray Vaughan. And yes, GLaDOS, in all her glory. I never truly got tired of that song, and now I'll be able to perform it in my bathroom on a regular basis.

All of these tracks will be available on July 19th for $1.99 apiece, with the exception of "Still Alive", which pays you with delicious and moist baked goods.
