Just have to say I absolutely love Song 4 u and Missing!
I felt like Melody could have been amazing too, but it felt like it dragged on till it got a bit better in the end.
The orchestra version of Song 4 u was nice, but it wasn't that different from the original haha
And finally, I like something else from Shinichi Osawa
The Remo-con remix is too long!
And yeah, Ayu needs to stay far away from dubstep >_>
However, I quite like the Melody remix <3
Overall, I give this release a 6/10
