I'm not really a crazed Glee fan but I recently watched their latest season and I must say their soundtrack is friggin awesome and last week's episode was the best!! The songs sang in that episode was amazing and just emotionally moving. I really can's stand Rachel's character in the movie but I have to admit her voice is wonderful. Definitely in terms of like "power" vocally, definitely Mercedes and Santana hands down! Listen to these songs, I really get the song and, it's just so beautiful to listen to. Listening to these songs while studying is good! haha!
