Out today: Carrie Underwood's "I Told You So"

Today marks the second Tuesday in a row that will see the release of a digital single by Carrie Underwood. Last week, Carrie's cover of Mötley Crüe's "Home Sweet Home" hit online retailers one day before it was used in Idol's results show for two farewell packages. This week, Carrie re-works her current single off Carnival Ride, "I Told You So," to include original artist Randy Travis on the chart, making it the second duet Carrie has recorded with a male country artist.

In addition to Carrie's release, another Idol champ sees a digital single release this week, as Ruben Studdard's "Together" drops today. Links to purchase the aforementioned can be found below:
