Cowboy Bebop is supposed to be a great classic and all that. I watched several episodes; they were okay but didn’t really grab me, and I doubt that I’ll watch the rest. The music is another matter. “Tank” is justly famous, but I like some of Yoko Kanno’s other tunes just as much. As with Christian Vander and Yuki Kajiura, Kanno’s lyrics are often in her own private language, such as here in “Green Bird.”
