Yeah, it's okay. Nice job.
Sorry man. It's a really great song and all, its just... the words are what I love so much about the original version. Its the humour in the original song that just gets me every time I listen to it. Don't get me wrong, this is a great song, I really like your version of it.
Great beat to it though. I really like the kinda techno feel you gave to it. Has a more upbeat feel to it, which I really like :P
Also, the "beepy" beat adds a little bit of GLaDOS to this song, which I think is also pretty awesome. I think it would've been cooler with an intro though, maybe like... a really funny GLaDOS or turret quote. They can be found in the resources folder in portal, under sounds. And also maybe a slightly longer ending, but apart from those points, awesome song. Nice work!
