I’m not including live albums as I’m generally not a big fan of most live albums, and a few of these are kind of a cheat since they only have 1-3 albums, but I think this covers everyone I own the full discography of (in alphabetical order):

Arcade Fire
The Beatles
Bedouin Soundclash
The Black Keys
Cake
Dr. Dog
Explosions in the Sky
Fleet Foxes
Flight of the Conchords
Gorillaz
Grandaddy
Kavinsky
Led Zeppelin
M83
moe.
Muse
Pink Floyd
The Polyphonic Spree
Radiohead
Secret Machines
The Strokes
Tenacious D
Traffic
The Who

I’m close with Queen, Primus, and the Chili Peppers. I’ll probably round out Primus and maybe Queen as well, but doubt I ever will for RHCP.
