A Great Big World & Christina Aguilera - Say Something

Hey MusicHeads!
It's Kai here. Today i'm going to jump out of my usual R&B songs and review a sad song. Usually i'm not depressed enough to repeatedly listen to a sad song, but Say Something seems to have just struck a chord with me. The song was originally released as a solo single in Axel's solo album ' This is the New year 2011' and only gained popularity after Christina Aguilera worked on the song. However, I don't think we should accredit the popularity of the song because Christina Aguilera was added. The song is great because of it's powerful lyrics and simple yet emotional composition. There is no doubt that Christina Aguilera also delivered the song powerfully. Her harmony seems to act as the response and adds so much meaning to the song ( as if they are talking to each other telling each other to say something). A great emotionally impacting song!
