The fact that some KEY scenes were builded around specific songs doesnt that tell you anything?.
Let me be even more clear, watanabe listened the Obokuri-Eeumi song, and build the entire scene of mugen almost dying
, do you get my drift?.
The same happend for several of cowboy bebop's key scenes.
I dont think many people understood what the OP was actually asking.
he didnt say "hey whats some anime with some good music in it?".
He asked for anime INFLUENCED by music. Big difference.
