This has been in my head for awhile. To all who have played Portal we all know the radio in the beginning with its great tune. And we know the iconic song Still alive. now the other day i was humming it to my self then it hit me. Having played still alive on my trumpet and humming the radio song i realized they are the same song. if you listen to the radio it does a sped up more upbeat funky tune of when GLaDoS sings Still alive. The beginning 2 parts can be compared if you sing one and speed up a hum of "this was a triumph" and so forth. Have a listen to 2 links I'll put here and tell me if i am right or im making bridges were none should be. Still alive Radio from beginning of game
