It might be echo by gorilla zoe
The song you're referring to is literally called "Eh, Eh (Nothing I can Say)"
it's from her "the fame" CD, which came out on.... it was released in the September of 2008
Eh, Eh (Nothing Else I can say) is the song I think your thinking about. Hope this helps!
unlikely but Lady Gaga- (eh eh)nothing else I can say could be it!
