By the end of the 1990s and into the early 2000s pop music consisted mostly of a combination of pop-hip hop and R&B-tinged pop, including a number of boy bands. Notable female singers also cemented their status in American and worldwide popular music, such as Beyoncé (with her solo career and as lead singer of Destiny's Child), Britney Spears, Christina Aguilera, Katy Perry, Lady Gaga and Taylor Swift. Also notable was the influence of hip-hop producers on popular music in the mid-late 2000s, who made the sounds first heard on Usher's "Confessions" and Nelly Furtado's "Loose" imitated throughout popular radio with artists Madonna, Akon and Lady Gaga. In the late 2000s into the early 2010s, pop music began to move towards being heavily influenced by the European electronic dance music scene, taking root in the college crowd through producers like David Guetta, Calvin Harris, Swedish House Mafia and Skrillex.
