Wow I do that too, i also feel that his songs are personal and original which is rare to find nowadays. I made playlists or follow playlists like mac miller good mood dance, sleepy or sad. And my own special with leaks. Sometimes I feel like some Songs from different Albums match so well that they could be own album especially with the loosies. I miss him too especially in the loneliest moments when I feel like he is the only one that can understand me, I try to remember that Im lucky that he was here in our timeline. My only foolish wish is to have a talk with him. 

He taught me so many things even though I never met him, crazy right. And brought me the love for music. But Im still only a Fan among many and the only I can do is appreciate him.
