In May 2005 the group returned to the charts, releasing a new song called "I Know", which featured a mildly controversial video based around domestic abuse. The song was again successful, peaking at #13 in Germany and #17 in Austria. Two weeks after its release their third album, Blue Tattoo, was released in various European countries and proved to be as successful as the previous album, charting at #4 in Germany and, unsurprisingly (as it included the Eurovision song "Cool Vibes"), Switzerland.
