The corollary of "My collection of (_______) probably makes me look like a bigger fan than I am," what band(s) that you love do you not own much of their material?
My top 4 bands are The Who, DT, Floyd, Maiden. For none of those bands do I own their whole studio discography. I am one short on DT (WDaDU) and Maiden (NPftD), and own 2 Who albums (plus a 4 disc greatest hits, a live album, and DVD) and a whopping 1 by Floyd (plus a live CD, 3 DVDs (by various members). I parted ways with a bunch of Floyd discs sometime in the 90s when 1) burned out on them and 2) needed money. I have a homemade CD of The Wall, with the extended "Empty Spaces," "When the Tigers Broke Free" and the "Outside the Wall" from the movie. But I don't own an official copy of The Wall, probably my favorite album of all time. Weird.
