LOS ANGELES - Australian singer Gotye has conquered the United States with his heartfelt pop tune “Somebody That I Used To Know,” but even as it hits No. 1 on singles charts, he is eager to become someone fans will always know for his “peculiar” sound. Gotye has enjoyed a rapid rise in fame, not just in the US but around the world, for the song of a failed relationship that features New Zealand artist Kimbra.
