One of the things that I noticed from Lurhmann's "The Great Gatsby" (apart from striking cinematography) was music - the soundtrack so perfect and so organically merged with the picture, that I simply cannot imagine the film without it - this OST is a backbone to the film.
This is one great soundrack (one of the best for me in recent years, but Buz Lurhmann always had a great ear for the music - just check out the OST for his "Romeo + Juliet" - Romeo And Juliet), Film aside, this is just a brilliant and diverse compilation album that I am sure will play on people's stereos this summer. I simply cannot stop listening to it since I downloaded it last night. Surprisingly, even performers that I disliked previously I am beginning to enjoy - everything is so lavish and varied, and just beautifully made.
If you loved the film - buy the soundtrack. If you did not love the film - buy the soundtrack anyway!
