Worst Rammstein album

The album "Rosenrot" indicates that Rammstein their sometimes very long creative breaks (the current lasts already 6 years) have an urgent need. But 2005 came directly one year after my opinion best album "Reise, Reise" with their worst album therefore. Although the songs "gasoline" are, "Rose Red" and "Help me" very good, but that's about it almost, because most other songs on the album very ballad-like, dull and anything but Rammstein are (a song is even in Spanish).
