Need help finding a song!

[rivillum]

I keep huming an old song, but i can't remember any of the lyrics, nor the artist or the song's title, so please help me find it! It's stuck in my head for months now. It's a song from the 2000's, something like 2005,2006, i listened to house back then [ministry of sounds etc]. It's a slow song and it starts with the guy humming like "aaah ah aah aah ah" then starts singing. It's all i remember about this song, so if it sounds familiar to anybody, please post your opinion. Thank you!
