Seeing the success of "Mr. Vocalist", Sony Japan opted to follow it up with another one. "Mr. Vocalist 2" was unique from the first because all the songs included in it were famous international ballads, and were voted in by fans either through the Internet or through mobile phone. Martin and Sony Japan lined up about 30 international ballads sung by women, such as "Hero" by Mariah Carey, "My Heart Will Go On" by Celine Dion and "Eternal Flame" by The Bangles. The top 12 songs were taken from the list and were covered by Eric and Sony Japan's team of top musicians. The resulting album was released on March 4, 2009, and topped the charts all over Japan at its debut. For months, it continued to move along the top five albums in Japan.
