watch the anime if you haven't there is a title track from there ~Blue have to say I love it. It's a bit depressing but the sound is awe inspiring. Hadn't listened to this before so thanks for sharing. There many great jazzy tracks from and for the anime :)
I have, even wrote a "review" for it :) https://steemit.com/life/@kevinwong/what-cowboy-bebop-taught-me-about-life
Indeed, one of the more evergreen soundtracks imo..
