Animal

The album received mixed reviews from music critics. Some appreciated its fun, carefree nature, while others dismissed it as juvenile and said that it seemed insincere. The use of Auto-Tune on the album to alter Kesha's voice was called fun by some critics, while others found it irritating and said it made it difficult to tell if Kesha could actually sing. Lyrically, the majority of the album's songs are based on Kesha's past life experiences of love, heartbreak, boys, and having a good time. Musically, Animal draws from the dance-pop genre, while incorporating elements of electro and electropop in its production and beats. The album attained chart success, debuting at number one in Canada, the United States, and Greece, while charting within the top ten in seven other countries. Animal was certified platinum by the Recording Industry Association of America (RIAA) for shipments of one million copies and has sold over 3 million copies worldwide. Four singles were released from the album. Its lead single, "Tik Tok", was released on August 7, 2009 and was a worldwide hit, reaching number one in eleven countries. It reached number one on the Billboard Hot 100 and stayed at the top for nine consecutive weeks. The song sold 12.8 million digital copies worldwide in 2010, making it the best selling single of the year; it sold 5,633,000 downloads in the United States alone, making it the sixth best-selling song in digital history. The album's second, third and fourth singles, "Blah Blah Blah", "Your Love Is My Drug" and "Take It Off" all achieved similar success reaching the top ten in multiple countries including Australia, Canada and the United States. The album's commercial success led to its nomination for the Juno Award for "Best International Album" in 2011.
