Tatu did not change their name and did not release new songs
The information about a change of name (it was said earlier that group "Tatu" was changing their name to "t.E.M.a.") and about a new song "Who, If Not Me?" are incorrect. According to the press attache of the group Alexandra Tityanko, "Tatu" is and will stay group "Tatu". They don't intend to break up or change their name. As for the song "Who, If Not Me?", it is not from "Tatu".
