The tracklist reveals more details on the 7 tracks and hints on a possible extra track with the mysterious title, "+ ???", listed on the bottom. We also see that Jonghyun had a big hand in the producing of this album as he's written or composed pretty much the entire lineup.

His pre-released song with Zion.T, "Déjà-Boo", has also gathered hot response, already topping real-time charts like MelOn, Genie, Bugs, Olleh Music, and Naver Music. His mini album release is expected to continue the success as Jonghyun branches out into various genres of music with the help of other big names in the industry.

The idol will also hold his debut showcase 'BASE of JONGHYUN' at SMTOWN COEX ATRIUM in Samseongdong, Seoul on January 8 at 7 PM KST. He will then have his debut stages on 'Music Bank', 'Show! Music Core', and 'Inkigayo' starting on the 9th before his album 'BASE' hits stores on the 12th at midnight KST!
