"Everything at Once" is a song written and recorded by Australian pop singer Lenka. It was released in November 2012 as the third single from her album Two.The song was originally released as the album's second promotional single in 2011, but after it was featured in a Windows 8 TV advert in November 2012, it was released as an official single. 　　Two, the album "Everything at Once" was taken from, suffered commercially, as did the album's two previous singles, "Heart Skips a Beat" and "Two". However, being sampled in a Windows 8 advertisement allowed the song to do much better, becoming Lenka's second most successful single, after "The Show".
