similar to song to say goodbye from placebo

[Faithii]

Hi,

I know it sounds kinda weird, but I just can't figure out the name of the song. I've heard it in the radio, in an American Eagle store and I think I might have heard it at Grey's Anatomy as well. It's similar to "song to say goodbye" from Placebo. I just remember the words "I wish" and alive? or somethin like that. I know, it's not a lot. Maybe someone can help. I think the song is pretty popular, just none of my friends could help me out.
Thank you.
