Song Lyrics, American Idol, and Heteronormativity

I’ll admit it. I love American Idol. I watched it since the second season, and I’ve been to two American Idol Lives concerts. It’s almost scary. But I haven’t let my love for American Idol cloud my heterosexism radar. That’s still very much intact. It beeps extra loud when performers change gender pronouns to connote a heterosexual relationship.
Two examples of this come to mind, and in my opinion, the performance suffered from the change of lyrics. Last season, Syesha Mercado sang “Me and Mrs. Jones,” a really great song. But she changed “Mrs.” to “Mr.” Yesterday, Casey Carlson sang “Every Little Thing She Does is Magic,” which is one of my favorite songs by The Police. She changed “she” to “he.” Also yesterday, Anoop Desai (my favorite contestant so far) sang “Angel of Mine” by Monica and changed all the “boys” to “girls.”
Come on. We all know these aren’t their own songs. They’re singing someone else’s song and should sing the lyrics that the original performer sang. If it sparks any rumors about their sexuality, who cares? The only people who would make that leap are idiots whose opinion don’t matter. Are these contestants really that insecure and afraid?
