The Vans Warped Tour rips into town tomorrow, and controversial singer / songwriter Katy Perry is on the bus.

Perry, who started her career as a Christian gospel singer, released a single last you called "UR So Gay" followed by another hit, "I Kissed A Girl."

Both songs created a fair share of controversy, but for different reasons. Some members of the LGBT community felt "UR So Gay" came off as homophobic, whereas "I Kissed A Girl" is criticized for using shock value lyrics to sell albums.

It's genius, really. Perry relies on the classic girl-on-girl fantasy to appeal to male listeners, which is exactly what Britney did with her naughty schoolgirl look. Simultaneously, Perry hooks female listeners, too, because -- let's just say it -- most ladies are bicurious.

However, "I Kissed A Girl" doesn't scratch the surface of the lesbian or bisexual experience. Lyrically, it's much weaker than songs by Ani DiFranco like "In or Out" or Jill Sobule's less contrived song also called "I Kissed A Girl" that came out in 1995.

If anything, "I Kissed A Girl" is closer to Cyndi Lauper's "Girls Just Want To Have Fun."

At the end of the video, Perry wakes up in bed with a man and it turns out her female-on-female frolics were only a dream. This suggests the song is merely a safe, mainstream attempt to snag listeners by capitalizing on straight people's obsession with the gay experience.

Not that there's anything wrong with that.
