And, because there is no such thing as "too much disco" :
Can there be too much Paris Hilton?
I was actually looking for one song that really stuck in my mind, unfortunately I don't know the title nor the artist. Only word I remember from the lyrics is "delicious". I tried looking up the playlist for the station I heard it on, but nothing there sounds like it. If I find it, you can be sure I'll post...

ServMe, could it be this one you're thinking of?

It's by Fergie of the Black Eyed Peas...
you mean the one from the pussycat dolls? I think that one has delicious in the lyrics somewhere. not sure about the title, though
Ash, no it's not the Fergalicious one, I considered it at first too and it sounds very alike but it ain't the one I'm looking for.
Actually Nadia gave me the pointer I was looking for : it is indeed Don't Cha by The Pussycat Dolls. Thanks!
