Right, I've heard a song a million times, I cant remember the words, except, a bit of it where it goes, 'oh.. oh a oh, oh oh oh..' in changing tune, its an indie song, by a band i probably know, but i only keep catching that bit, and the end of it, i heard it on hollyoaks and on the radio, but i can never ever ever remember the title.. Also: it's a male singer, if that helps.
Hmmm it might be Silent Sigh by Badly Drawn Boy. But obviously not sure as your description's a little vague! I think it was on Hollyoaks the other week as well (unless I'm just making things up).
I can't remember when teh song Im thinking of was on hollyoaks, but if it was in teh last week it will say on the website the songs played during last week's episodes...so you could try there?!
