Miranda Lambert and Carrie Underwood together? So obvious, right? Their duet on Sunday's (May 18) Billboard Music Awards was insanely good. Yet as satisfying as it was, it just left me wanting for more.

In 1993, Reba McEntire and Linda Davis had a huge girl/girl duet with "Does He Love You." Aside from the undeniable vocal power, that one may have been huge because the world needed a song where a man's wife and his mistress try to out-do each other with how much the two-timing bastard loves them.

Then in 2008 there was that "buh-bye, you sleazebag" song from Kellie Pickler and Taylor Swift, "Best Days of Your Life." As in, you already had them when you were with me. K-Pick and T-Swift even wrote it together. And the cheater even gets hit by a bus in the video. It was that good.

But that's it. I can't think of any other big country hits that are duets by two females. On the flip side, country's got enough guy-and-guy duets to make you think men are the only gender capable of coming together in song.

If the Lambert/Underwood collaboration lit a fire under the asses of country songwriters and I could have any girl duets I wanted, this would be my starter wish list:

1. Faith Hill and Martina McBride

2. Reba McEntire and Taylor Swift

3. Carrie Underwood and LeAnn Rimes

4. Miranda Lambert and Patty Loveless

5. Kellie Pickler and Sara Evans

6. Ashley Monroe and Rosanne Cash

7. Brandy Clark and Trisha Yearwood

8. Shania Twain and Dolly Parton

9. Loretta Lynn and Miranda Lambert

10. Kacey Musgraves and Leah Turner
