It seems like, everywhere I've looked recently, there's Katy Perry and this "I Kissed a Girl" song.

YouTube - Katy Perry - I Kissed a Girl (Official Video)

First, I heard a trance remix of this song. Then I saw her performing the song live (on tv) at one of those Times Square New Years celebrations. Then I started hearing the song coming in and out of commercials on television and radio. Then somebody was singing I Kissed A Girl or it was referenced in some way on American Idol earlier.

I guess my question is: Is this the newest thing out there, or am I like six months behind and is every hip person in America already sick of Katy Perry?
