OK,I bought it at Virgin, and all it said was "DJ Tiesto Limited Edition Remixs"

NO FREAKING TITLES ANYWHERE

So bought it anyway hoping it wasn't something I owned already, and it wasn't.

So on A side is a remix of what sounds to me like Radiohead, The Darkness, or Muse??? Nice guitar riff and the voice sounds like one of these three bands.
Side B is a female vocal, very long track, great bassline but no clue what it is, I couldn't even recognize the voice, I'm assuming that it's another remix of a band with a lead female vocalist (just because of side A)

Anyone help me?

perhaps the 1 u have is Radiohead- Street Spirit (Tiesto Remix) and the other side is Madonna - Die Another Day (Tiesto Remix)
