You know we’re list whores at PopWatch, which is why we’re loving retroCrush’s 25 Greatest Duets of All Time. (In fact, we’d want to be alone with it, if the video links still worked.) You’ve got everything from Jenna Fischer and John C. Reilly (“Let’s Duet”) to Ella Fitzgerald and Louis Armstrong (“Summertime”). Well done.

Which other tracks would’ve made your personal list? Off the top of my head, I could never deny Reba McEntire and Linda Davis (“Does He Love You,” below), Kenny Rogers and Sheena Easton (“We’ve Got Tonight”), and David Frizzell and Shelly West (“You’re the Reason God Made Oklahoma”).
