Of those two, I prefer Stein Um Stein by a mile. Was Wo Bist Du even one of the songs that was recorded during the Reise Reise period? Because about half of Rosenrot was actually new stuff, and while not as good as Reise Reise as an album it had a number of great songs for me... Spring, Rosenrot, Te Quiero Puta!, Hilf Mir, Stirb Nicht Vor Mir, and most of all Zerstören

Looking forward muchly to one of the guys' solo/side-project, whichever it is...
Incidentally, I ventured into HMV for the first time in ages today, but my fast-growing overdraft stopped me from buying any albums. I just wasted 9 quid on singles instead, as you do. (Muse - Starlight x2, Lazyboy - Underwear Goes Inside The Pants, Little Man Tate - House Party At Boothy's)
