Perfect Day is the second studio album released by German Eurodance act Cascada. The entire album was produced by the act's two DJs, Yanou and DJ Manian with vocals by Natalie Horler. Like its predecessor, the album is comprised heavily of uptempo Eurodance tracks, many of which are cover songs. This album, however, features covers of songs from the early to mid 2000s of the rock and country genres, with the exception of Because the Night (originally released by Patti Smith) which was released in 1978. Two edited tracks, "Endless Summer" and "I Will Believe It" that were previously recorded under the Siria name are also featured. Musically, the album is composed of Eurodance tracks with euphoric trance synths, drum programmings with a tempo over 140 beats per minute, and Europop lyrics. Lyrically, the songs are composed of love, partying and romance.
Critical reception of the album was negative, with many critics disliking the repetitive nature, that all the songs on the album sounded similar, and the lack of character and originality. The album has sold about 3 million copies worldwide. There was a total of five singles released from the album. Unlike their previous album, Perfect Day only had one major hit single worldwide. "What Hurts the Most" peaked in the top ten in six countries, including Austria and France and was certified gold in the United States for sales exceeding over 500,000 downloads. "What Do You Want from Me?" and "Because The Night" peaked in the top sixty in Austria, Germany and the United Kingdom. The last two singles, "Faded" and "Perfect Day", were released in the United States and Canada and failed to garner any chart success.
