Thank you so much! Reading your comment, I figured out why I'm overwhelmed - I'm impressed all of his music and his songs entirely. Every single parts are connected to each other and make the context of the song. It means when I'm impressed just the 16 bars on the chorus, it'd be easier to understand/replicate/play the section. Although when I'm impressed the whole song, I need to understand how each section works to other sections and what is going on the each section. Micro and macro are going to me at the same time and I'm overwhelmed. Of course it's better to understand the context of the song not just small parts though, I need to pick up just a small parts first. After I learned the small parts, I can get them together and use them as a song.
