These musicians have created some excellent Portal-inspired songs spanning a vast range of styles.
Wearethemassacre – “Into Your Heart”
What better way to respond to GLaDOS's “Still Alive” than a musical love ballad?
Nathan Pinard – “We Work for GLaDOS Now”
The turrets sing a clever bluegrass parody of "In the Jailhouse Now".
Seren Morphile – “Cake Is A Lie”
This may be the catchiest metal song about cake ever written.
The Hamster Alliance – “Portal Music”
A full album of ambient tracks in the theme of Portal's own soundtrack. Many of them have gone on to appear in various fan-created Portal maps.
The Hamster Alliance
“In the Cake”
