Today only, Amazon has the Disney Sing It: Pop Hits on sale for just $19.99. This features songs from favorites like The Jonas Brothers, Taylor Swift, Cobie Caillat, Hannah Montana, Demi Lovato, and Jesse McCartney. This is just the game and does not include the microphone, but is still the lowest we've seen. Shipping is free with $25 and there is no sales tax (except KS, KY, ND, NY, WA).
