Can anyone identify this song?

I can only give a vague description of this song but it used to be popular at college. I have no idea of it's age apart from it can't be newer than 2008 because that is the year I left college. But I heard it play on the radio the other day which seemed like a unlikely place to hear it.

It's a very simple song with no drum beat as such. It's got an unusual rhythm and is quite repetitive in nature.

The song sounds like it has basically 2 looping keyboard parts throughout the whole song.

One of those keyboard parts is a single note possibly a high G sharp which is played every 4 or so seconds.

The other keyboard part has got a "ooo eee-eee" rhythm to it.

It has lyrics but its so quick it's difficult to pick up any specific words. It's a male voice but it sort of says it in a gibberish manner. It's not singing as such and there isn't much variation in notes.

Hoping that is enough to go on, cheers :)
