None of the songs appeared on the album was released as a single. Instead, two of previous released materials were featured as bonus tracks; her own interpretation of the song "Snow Umbrella" originally recorded by Shizuka Kudo in 2008, and new recording of her recent single "Just Save Love" released in 2009. The song "It's a Dream" was simultaneously covered by Makichang (then-23-year-old female singer-songwriter who've contracted with Nakajima's management office). Her version was released as a double A-Side single with her original composition "Anata no Inai Heya ni Nareru Hi ga Kuru Made" by VAP Records.

Midnight Zoo debuted at #5 on the Japanese Oricon Weekly albums chart, making Nakajima the first female solo artist to have had the country's top-10 charting albums in five consecutive decades — three male musicians have already set this record; Eric Clapton, Eikichi Yazawa and Masashi Sada. The album has sold over 40,000 copies as of December 2010.

All songs written and composed by Miyuki Nakajima, arranged by Ichizo Seo (except M1/10 co-arranged by Satoshi Nakamura, and M11 co-arranged by Shingo Kobayashi)
