Just back from Ibiza .
Kept hearing this tune when I was recovering by the pool but was in no fit state at the time to ask the name, now I can't get it out of my head.
The lyrics;
"do you know, do you know, do you know what ya doing to me baby, do you know what I really need (well I think it's need). It's a tech-house song, the singer has a really deep voice for a woman (it might not be a woman actually).
I think it's really popular. Any suggestions would be appreciated. Thanks
