He sets the big difference from an ordinary new singer and he appeals a great deal of Oriental images with unique charms. He's the newcomer who has a professional mind.

The title song, ‘Bad Guy‘, has the hard Hip-Hop sounds & the powerful vocals. This is a song of 'Park Jin-Young' who is known as the best hit maker. You can feel the heart and soul he put into 10 songs as the production period took 2 years.It starts with a woman’s sad and near screaming narrations, and followed by the orchestra’s tragic sounds and Rain’s charismatic voices with a strong Hip-Hop rhythm based on heavy R&B. The exquisite harmony between the greatest powerful masculine image through the strong beat with the harsh breath and the girl's sob sounds makes this song sad and heartfelt.
