With the exception of "Call/I4U", Komuro continued to work with AAA through to 31st single "Sailing". All of the songs on their sixth album "Buzz Communication" were composed by Komuro. In 2011, they released their second compilation album "#AAABEST" and it went on to become their best selling album at the time, as well as becoming their first number one album on the Oricon weekly charts. Starting from "Call/I4U", the group also gradually shifted away from the "lead singer" position and more equal singing opportunities were given to all members.
