At the beginning of the 2000s, dance-pop music was still prominent, and highly electronic in style, influenced by genres such as trance, house, techno and electro. Nonetheless, as R&B and hip hop became extremely popular from the early part of the decade onwards, dance-pop was often influenced by urban music. Dance-pop stars from the 1980s and 1990s such as Britney Spears, Christina Aguilera, Madonna, Janet Jackson and Kylie Minogue continued to achieve success at the beginning of the decade. Whilst much dance-pop at the time was R&B-influenced, many records started to return to their disco roots; Kylie Minogue's albums such as "Light Years" (2000) and "Fever" (2001) contained influences of disco music, or a new 21st-century version of the genre known as nu-disco; hit singles such as "Spinning Around" (2000) and "Can't Get You Out of My Head" (2001) also contained disco traces. In Madonna's case, her album "Music" (2000) contained elements of Euro disco, especially the successful eponymous lead single.
