They Record, I Buy

Everyone has "their" band, the band that your friends most closely associate with you. I have a few guesses as to which bands people associate with me (in most cases they might be wrong) but there are many bands out there whose albums I keep buying regardless of whether or not I think the previous album was great. Not to say that the bands in list didn't make great albums all the way through, but some definitely had some duds according to the masses.

Here is the list as they pop into my head. Bands must have released at least four original studio albums to be eligible, and I have to have at least four of their albums.

1. Deftones
2. Mars Volta
3. Tool
4. Thrice
5. In Flames
6. Killswitch Engage
7. Rob Zombie (including White Zombie)
8. Stone Temple Pilots
9. Smashing Pumpkins
10. Lamb of God
11. Opeth
12. Drive-By Truckers
13. Disturbed
14. Helmet
15. Chemical Brothers
16. Slipknot

Not quite meeting requirements but after their next release...
Mastodon
High on Fire

Bands that didn't make the first list because of a hiatus in buying but I have begun listening to them again and buying subsequent albums.
1. Megadeth
2. Fear Factory
3. Clutch
4. Marilyn Manson
5. Ministry
