I've heard it time and again, and it's happened to me before, but man oh man:

I've been singing along to Beirut's "A Sunday Smile" and the other songs on the same album for years now, and only just wanted to look up the lyrics.

There's a lot of excerpted dialogue in it from French media, and I was curious about the portion in "A Sunday Smile", the source for which someone was kind enough to post, along with an explanation.

That part of the lyrics, I didn't know. I also didn't know any of the rest of the lyrics.
