"Can't Get It Out of My Head" is a song written by Jeff Lynne and originally recorded by Electric Light Orchestra (also known as ELO).
First released on the band's fourth album Eldorado in September 1974, the song is the second track on the album and follows "Eldorado Overture". The song was released in November the same year as a single.
The song became the band's first top 10 single in the United States, reaching number 9 and helped boost public awareness of the band in the U.S.; however, back in the UK the single and LP failed to chart.
In 1978, it was included as the lead song on the four-track The ELO EP (UK release), reaching number 34 on the UK charts. The song has appeared on many ELO compilation albums.
