Idk about best but this is one of the more impactful songs for me that's very lyrically strong:
Milo - An Encyclopedia

Specifically the verse leading up to:
Darrien Hunt cosplaying was killed for his hobbies
And I love Mugen too
And that's the thing
I love Mugen too
(in reference to the character Darrien was cosplaying as)
I'm not a big book reader these days but I'm so used ereaders now that I feel like it's more comfortable than reading a big book. Definitely easier to carry around and read in low light conditions (if yours has a backlight) and personally I don't think there's much loss in "fidelity". Also, downloading books for free is nice.
