Finally  “Album Mode” is available in the iTunes Sound Check feature which is enabled in the itunes radio by default. Itunes sound check helps to even out the differences between different songs in the itunes library or on a itunes radio and to stop the volumes from jumping up and down in shuffle mode. But this is not needed in the case of albums. An album is a carefully constructed sequence of songs, thus “Album Mode” facilitates to keep a balance and makes quite songs quite and the loud songs loud.
