July 2005, Hecker was invited to Seoul, South Korea, to play two gigs, and in June 2006, he was sent to Taipei, Taiwan, to give two concerts, after the Taiwanese record company Avant Garden Records had released his first three albums in Taiwan in August 2005. I'll Be a Virgin, I'll Be a Mountain In summer 2006 he changed from Kitty-yo to V2 Records and released his fourth studio album, I'll Be a Virgin, I'll Be a Mountain (again produced by Guy Sternberg) in Europe, South Korea and Taiwan in September 2006. Unlike his three predecessors, which Hecker had recorded on his own for the most part, the album was brought about with the aid of a number of studio musicians, amongst them Snorre Schwarz, Hecker's live drummer. Sharon O’Connell from British music magazine Uncut reviewed I'll Be a Virgin, I'll Be a Mountain in the magazine's December issue 2006: »Comparing Hecker to Chris Martin may be something of a backhanded compliment, but it’s an indication of the 29-year-old’s potential reach, rather than an indictment of aesthetic weediness. That said, "I’ll Be A Virgin…" is a hushed introspective affair, its sweetly mournful melodies augmented by tasteful string arrangements and carrying somewhat poetically strained lyrics ("Wilted Flower" distinguishes itself on that count). Toward the album’s close, a dreary sameness sets in; simpler songs like the folky "Messed-up Girl" are Hecker’s most effective.« In October and November 2006, Hecker went on his fifth European tour, followed by concerts in Taipei and Seoul in November and December of the same year, and finally by him opening for Irish musician Duke Special on his tour of Europe in March 2007. Around that time, Hecker's song Dying was chosen as background music for a commercial of electronics group Samsung, broadcast in South Korea and China. In early 2007, Hecker recorded an EP, entitled Once I Was, especially for the East Asian market. The record contains cover versions only, and was released, along with a best-of-compilation of his songs, in Taiwan, South Korea, and for the first time in Mainland China (there entitled I Am Falling Now) in May respectively June that year. The album offered the opportunity to send Hecker on his fifth tour of Asia, leading him through Taiwan, South Korea and Mainland China in July of the same year. In November 2007, Hecker's former record label Kitty-yo released the live album Live Radio
