(2005). I te tau 2005, i whakaatuhia a Grey i nga waiata a te roopu hip hop o Amerika a Fort Minor, "Where'd You Go" me "Be Somebody". I tukuna a "Where'd You Go" hei takitahi i te Paenga-whawha 14, 2006, me te riipene ataata e whai ake nei i muri mai. I angitu te waiata i te hokohoko, a, ka mutu ko te wha o nga toa i runga i te US Billboard Hot 100 chart, a, i whakamanahia ano hoki e te Recording Industry Association of America (RIAA). I muri i te mahi tahi me te kaiwhakanao puoro a Jonathan Ingoldsby, i tukuna e Grey tana pukaemi tuatahi, i tapaina ko Like Blood Like Honey, i te Pipiri 6, 2006, i raro i te Warner Bros. Records. I eke te pukaemi ki te nama 35 i runga i te papaanga a Billboard's Heatseekers Albums. I roto i tenei wa, kua tae mai a Grey ki nga waahi whakatuwhera mo nga haerenga konohete me Jamie Cullum, k.d. lang, Daniel Powter, Teddy Geiger me Duncan Sheik.Na ona hononga mai i Machine Shop Records, ka piri piri a Grey ki nga hononga Linkin Park Styles of Beyond me Apathy. I whakaatuhia ia i runga i nga ara e rua i tapaina ko "Victim" me "No Sad Tomorrow", mai i te pukaemi tuarua a Apathy, Wanna Snuggle? (2009). I haereere a Grey hei waahanga o te roopu a Duncan Sheik me te awhina nui ki tana pukaemi 2009, Whisper House. I te tau 2009, i puta a Grey hei kaiwaiata tautoko i te pukaemi tuatahi a Yohanna, Butterflies and Elvis. I te marama o Akuhata 2009, i raro tonu i te ingoa Holly Brook, i tukuna e ia tana waiata "It's Raining Again" me tana ahua ki tetahi kaupapa whakatairanga mo Ciao Water. I te timatanga o te tau 2010, i mahi ia i roto i te putanga whakaari o "Whisper House", e takaro ana i tetahi o nga kaiwaiata wairua e rua, me David Poe. I te Pipiri 10, 2010, i tukuna e ia te whitu-waiata whakaroa (EP), O<unk>Dark:Thirty. Ko te whakaputa o te EP i whakahaerehia e Duncan Sheik me Jon Ingoldsby.  Pātai: I tehea rā i tukuna ai e ia a O'Dark:Thirty?
