completist 

A person, usually a fanboy type, who desires to collect all the work of a specific author or artist. Most common with jazz and rock musicians, where studio outtakes and live performances are collected and traded. Generally mildly derogatory.

You'd think he'd give it up after the fourth Dick's Picks CD, but truth be told he's just an over-the-top Dead completist.
