I buy albums from bands that I feel deserve support.
I'm right there with you on buying stuff from bands that deserve support, but I disagree with your approach. In my mind, a band that releases a crap album *doesn't* deserve support, and, assuming that my purchase sends *any* sort of message, it would be the exact opposite of the message I want to send. "ooh, sweet, Neil bought that crap album? I guess we must be on the right path!" Noooo!
There is far too much music out there for me to mourn the death of any single band. Sounds cold, but that's the cold reality.
If I supported bands I liked by buying all their albums, I'd have no money, because I listen to way too many artists. Some stats:
Between 2007-2009, I bought 147 albums, from 132 different artists. Which is quite close to 1 album per artist (1.11 to be exact). There are only 11 lucky artists who got multiple purchases from me. And note that I'm going by purchase date, not release date, so it's not like the numbers are almost 1:1 because bands only released 1 album in that period; I could have picked up whole discographies for the bands, but in most cases, I don't do that.
I feel that there's such a variety of music out there to explore, and spending too much time with multiple albums from the same band gives me too much of the same. The spaces between bands are usually larger than the spaces between albums from a single band, so buying 100 albums from 100 bands allow me to cover a lot more ground than buying 4 albums each from 25 bands. So, I guess even if I didn't do the sampling/previewing that I talked about earlier in the thread, I still wouldn't have much of a blind-buy list, because I just tend not to be a dedicated subscriber to the output of any one band.
For the record, here are those lucky 11 artists:
Dillinger Escape Plan (Miss Machine, Ire Works)
Enid (Seelenspiegel, Gradwanderer)
The Gathering (Souvenirs, A Noise Severe)
Gogol Bordello (Gypsy Punks, Super Taranta!)
Hammers of Misfortune (Fields, Church of Broken Glass...doesn't really count)
Heavens Gate (In the Mood, More Hysteria)
Iced Earth (Framing Armageddon, The Crucible of Man)
Negura Bunget ('n crugu bradului, OM)
Novembre (Dreams d'Azur, Classica, Materia, The Blue)
Tomahawk (Mit Gas, Anonymous)
Tyr (Eric the Red, Land, By the Light of the Northern Star)
Surprisingly, a lot of those albums are pretty similar to each other, sort of contradicting what I would have expected. But the bands themselves tend to be pretty unique, so I guess the multiple albums fill the spots that albums from similar bands would fill, if bands similar to Tyr or Negura Bunget existed.
