In some ways, "Some Nights" is an even more important song for Fun. than their breakthrough hit, "We Are Young." Any band can have a fluke hit. Rick Dees had a hit. It didn't make him a career artist. But as soon as "Some Nights" started blowing up on the radio it became clear that Fun. were a serious talent. The song is even catchier than "We Are Young," and Top 40 radio has been spinning it non-stop for weeks. Right now it's sitting at number eight in its 43rd week of release. Now comes the big question: do they have a third one in them? Paula Cole had two hits, too. The pop world can be cruel.
