Cowboy Bebop Tank! THE! BEST! was the final album by The Seatbelts before they disbanded in 2004, containing 12 tracks including three all-new songs written for the 2005 video game Cowboy Bebop: Tsuioku no Serenade, featuring the vocals of Ilaria Graziano. Other songs are selected from the TV series and the movie Cowboy Bebop: Knockin' on Heaven's Door. The first pressing of the CD included a bonus sticker.
The band split after this recording but reunited in 2020 during the pandemic and recorded the soundtrack for the Netflix series.
