The title song, 'It's Raining' is a dance music combined with the Hip-Hop beats of tremendous energy and the analog tone of strong techno sounds. If 'Running Away from the Sun' of Rain’s 2nd album is near tender and sensitive R&B, 'It's Raining' is a strong Hip-Hop only for Rain's magnificent stage.It will capture the eyes and ears of the audience with a new powerful dance that Rain developed with his heart and soul for a long time. Park Jin-Young is also quite impressive with his new upgraded sounds and music through the advance into America.

'It's Raining' doesn't mean 'it rains‘, but ‘Rain is performing'. This is a song rendered a shudder and excitement that Rain feels on the stage. The moment they watch his first stage, all audiences will not believe their eyes and ears.
