My musician friend CLBGM wrote to me on MAL: "There's a lot of people on the internet who accuse Sawano and Kajiura of recycling their music (the cheap phrase 'all their songs sound the same'). That doesn't make sense at all. Since the times of Bach and Mozart, composing music is about reusing musical entities that are part of your own 'musical language', manipulating and combining them in a creative way (this is the subjective part that determines if you like a composer's work or not). A musical entity alone may be 'generic' (when a lot of composers use the same entity in their music) most of the time, but all entities used by a composer together make their music distinguishable. In my case, the more I understand the composer (a composer I like to begin with) the more I enjoy his/her music."
For those wanting to hear a native German speaker sing the German lyrics, PaperBlossom has covered Vogel im Käfig, Flügel der Freiheit, and Blumenkranz. https://www.youtube.com/user/Paperblossom/videos She has a cover of ətˈæk 0N tάɪtn in the works.
I'm biased so yeah I prefer his scores for Sengoku Basara more. He magnificently composed such "in-your-face" kind of soundtracks for Basara (iirc he said this in Sengoku Basara: The Last Party bonus, feel free to correct me)
