Query: Carrie Underwood sings in Some Hearts - my review:

Pros Some Song Variety - Country with some pop mixed inUnderwood's Vocal Range - Can hit the high notes with the best of themDepth of Instrumental - Piano, guitars, strings... It has it allCons It is a Country Album - This is only a con if you're looking for a LOT of variety.Less than Incredible Tracks - Like all CDs, this one has a couple songs that won't wow you.Substance - Some would say she doesn't move much beyond her AI image her. But is that bad?
