Bands you like so much, you get everything you can.
 

I like to collect everything of a band once i deem it worthy,
anybody else?

I have everything I can find of:
Bowie
Nin
Bjork
Radiohead (new dvd out, don't have it)
Pearl Jam (not all the brown cd's, but about 35 - 40 of them)(out of 170 or so, sigh.)
Alice in chains

And I'm collecting:
The Mars Volta (lots of picture records to go)
Tori Amos(2 cd's and a new dvd to go)
Tom Waits( bout a third to go)
Marilyn Manson(couple of old early stuff to find, plus for some damn reason, I still don't have him doing golden years,was this a B-side to a single?)
PJ Harvey( 2 to go)
Nick Cave(3 to go)

By the way, I only collect singles that have B-sides i can't get anywhere else.

Add me to the Bjork club.

i own almost everything that Isis and Circle Takes The Square have done.

Tom Petty

I have everything Zeppelin, and almost everything Page & Plant, greatest hits included.
