lyrics are something like "it's killing me, I've got something in me, I've got an e"
I've searched everywhere this last couple of days, you know when something's stuck in your head - well, I'm reckoning it was around 10 years ago - same sort of era as Dejure, Sanctuary - I did think it was from a Seb Fontain CD (prototype) but may have been Ornadel or Oakenfold.
So, "it's killing me, I've got something in me, I've got an e.........."
Sounds very much like it's 'Signum - What Ya Got 4 Me'. A trance classic!
There are a fair few remixes of this so you might have to look around for the specific mix you are after. I've posted a link to the original mix (and my fave mix!). The vocal drops around 3 minutes in.
