(oooh...You suck my soul out)
Angels melting in the dead of night
And the super Sonic's sucked into the supermassive

The story:

I was singing at kareoke (with my eyes shut, of course) and when I went back to sit with my friend and she kindly informed me of the correct lyrics - whilst laughing in my face :D
I always thought Muse's lyrics are pretty weird, so it didn't seem that unusual that these were about angels melting and Sonic the hedgehog...
