"Tank!"

"Tank!" is the series' opening song. The song, written by Yoko Kanno and performed by Seatbelts, has an extensive alto saxophone solo played by Masato Honda, as well as a fill part at the end. The song is a big band jazz piece in a Latin-infused hard bop style with a rhythm section that combines a double bass and bongo drums.

"Tank!" is primarily an instrumental piece, though it does feature some spoken male vocals (provided by long-time collaborator with Kanno, Tim Jensen) in the introductory portion of the song, thematically jazz in style. The vocal portion provides a lead-in to the instrumental portion, and its final lyrics, "I think it's time we blow this scene. Get everybody and the stuff together. Okay, three, two, one let's jam", signal the beginning bursts of the majority, purely instrumental end of the song.

It has been featured on the soundtracks to the series and was used on the preview for TV series My Own Worst Enemy. Figure skater Kevin Reynolds performed his short program for the 2016 Canadian National Figure Skating Championships to "Tank!", and did it dressed as Spike Spiegel.^[1][2]

"The Real Folk Blues"

"The Real Folk Blues" is the first ending theme for Cowboy Bebop. The song was performed by Seatbelts, featuring vocals by Mai Yamane. The song was composed and arranged by Yoko Kanno, with lyrics by Yūho Iwasato. The track appears on the series-related album Cowboy Bebop Vitaminless (カウボーイビバップ ビタミンレス, Kaubōi Bibappu Bitaminresu). The song is one of few songs in the series to be sung in Japanese.

The song is not used for the end credits in "Jupiter Jazz, Pt. II" (the song used for the end credits in "Jupiter Jazz, Pt. II" is "Space Lion") and the finale, "The Real Folk Blues". However, an alternate version of the song entitled "See You Space Cowboy..." plays during the final episode as the prelude to the climax. It appears on the Cowboy Bebop Blue album as a bonus track.

Cowboy Bebop

Cowboy Bebop Remixes: Music for Freelance

Cowboy Bebop Remixes: Music for Freelance (カウボーイ ビバップ リミキシーズ ミュージック フォー フリーランス, Kaubōi Bibappu Rimikishīzu Myūjikku Fō Furīransu) is a collection of songs remixed by popular American and British DJs, including many from the popular Ninja Tune label. Mr. Scruff spoke to British magazine Impact of his remix of Cat Blues, telling Andrez Bergen that he chose it "as it was a great, old sounding tune, simple with loads of personality. The parts were so well recorded that it was a pleasure to remix! I chopped it up into a kind of stuttering drumbox jazz wobbler".^[13]

The premise of the album is that the CD is a recording of a pirate radio station, and each song is humorously introduced by the DJ (Watanabe), in English. These tracks are called the "Radio Free Mars Talks". They are credited as follows:

• Script: Shinichirō Watanabe, Dai Sato
• Translation: Agnes S. Kaku
• Narration: Peter Duimstra

The Cowboy Bebop Boxed Set includes four regular size CDs, one bonus Mini CD, and a 52-page booklet (in Japanese). The booklet includes trivia, track listings, interviews, and lyrics. Disks 1, 2 and 3 contain new and previously released tracks from the series, performed by Seatbelts. Disk 4 contains live tracks from Seatbelts on tour, as well as some unreleased movie tracks. The dialogue tracks are not songs, rather, they are vocal samples taken directly from the Japanese version of the series. It was released on June 21, 2002, and is now out of production.

Sean Westergaard of AllMusic gave the boxed set four out of five stars, citing its eclectic blend of genres and an appeal going beyond anime fans to "any adventurous listener", but also mentioned that the spoken dialogue tracks detracted from its accessibility.^[14]

The scripts for the dialogue tracks are credited to Shinichiro Watanabe and Dai Sato and the translation was done by Agnes S. Kaku.

Tracks in bold are exclusive to this boxed set.
