Help me find this song!!!?

Ok... I posted a similar question before and got the answer I was looking for, but this time I don't have quite as many lyrics to use... but I do have other songs that sound like it which may help. I'm a vendor for Home Depot and keep hearing this song that I actually hate, lol, and I want to find out who it is (don't ask).. the song itself sounds like KT Tunstall's "you're not the one for me"... it has that same kind of vibe and note progressions... the singer is a girl and also sounds quite a bit like her (thought it was her but now I'm not so sure). Either way... the only lyrics I have to go on are what I'm assuming is the "chorus"... she says "oh oh oh... oh oh oh... oh oh oh.. (and maybe one more oh oh oh)... it's very distinct though because she harmonizes with herself in octaves that don't go together so the whole part sounds EXTREMELY out of key... hence... why I hate the song, lol. Either way... if anyone knows who this might be feel free to let me know. Thanks! again... sounds like KT Tunstall and her song "you're not the one for me" and the "chorus" has several back to back out of key "oh oh oh's".
