Information
Funky Days! (ファンキーデイズ!) is the fourth single by Japanese hip-hop dance group Lead released three months after their debut studio album Life On Da Beat on July 30, 2003. The single performed well on the Oricon Singles Charts, taking #10 for the weekly ranking, and remained on the charts for five consecutive weeks.

The single was released as a standard CD and came with three bonuses: one of five possible trading cards, a URL where fans could download a Lead-themed wallpaper and screensaver, and a Lead 2003 Summer Campaign postcard. Along with the title track and its corresponding instrumentals, the b-side "All My Life ~Manatsu no Umi Monogata~" (ALL MY LIFE ～真夏の海物語～ / Midsummer Ocean Story) was included, as was a 2003 remix of their debut song "Manatsu no Magic." The 2003 remix was done by AKIRA, who created the side-project PALM DRIVE. While the music video was released for syndication upon the single's release, it did not become available to purchase until the release of their first video compilation, Lead Movies 1, in September of that year.

"Funky Days!" was written and composed by musical composer Shinji Tamura, with lyrics written by lyricist Atsuyuki Enokido. The song carried both elements of pop and hip-hop music. The coupling track, "All My Life ~Manatsu no Umi Monogata~," was written and composed by Yasushi Sasamoto.
