 The actual phrase from EoCCM is ""Two years from their founding, they were the most popular Crhistian act in the world, and three years later they had become the most popular overtly Christian act of all time."" I too would argue that it should be ""to date"". p. 239. The recent edit, which I reverted, read ""In 2002, the Encyclopedia of Contemporary Christian Music called DC Talk ""the most popular overtly Christian act of all time."""" First point is that this is a band or group, not solo artist. Second, I don't know what measure the editor was using to determine popularity. What I read above regarding Kansas (they were a mainstream band first and then a few members became Christian, but they never really considered themselves a Christian band), P.O.D. (how popular were they in Europe, Japan, and Latin America?), Switchfoot (they don't think they're a Christian band), etc. It carries quite a bit of POV, but it would be nice to qualify the statement.
