They used to be my favorite band too. I still love them a lot, but I found better stuff (which I used to think was impossible).

I have:

Albums

- Mutter
- Sehnsucht
- Herzeleid
- Reise Reise (the first time they disappointed me, for most songs on the album)
- Live Aus Berlin

Singles

- Mutter
- Links 234
- Sonne
- Feuer frei
- Ich Will
- Mein Teil

DVD

- Live Aus Berlin

For those who may wonder, their next album is called "Reise Reise (Vol.2)" and is out October. They've thus far played the new song "benzin" (gasoline) live in berlin, but no recordings.
