Anyone here...

me. don't see a point in learning note for note somebody else's song.

i check out passages i think are cool and study that, but ultimately it's about writing my own music.
 
I don't. I could waste time learning a whole song that I won't be playing in a few months, or I could just take the riffs that I enjoy and apply them to my own music. Obviously, I take the latter. It's helped me as a musician to come into my own style.
