it as a CD single in Switzerland on March 4, in France on March 22, in Italy on May 18, in Germany on May 30, in Australia on June 27, in the United Kingdom on July 25, and in Canada on July 28. The Swiss and Canadian release also included "Stupid Like This", a non-album track, while the Italian, German, and Australian versions included "Stupid Like This" and "Lost on The Stoop". In France and the United Kingdom, both versions were released, and the British release also contained the music video for "Bad Day". A live-recorded version for Austrian radio station Hitradio Ö3 was included on the 2005 EP Free Loop. On August 6, 2008, an EP live from Tokyo was released exclusively on iTunes and it included "Song 6", "Free Loop", "Best of Me", "Love You Lately" and "Bad Day".
