"Finish What Ya Started" is a song by Van Halen taken from their 1988 album OU812. The song is different from the band's usual style, with influences from American blues and country music. The song is noteworthy as Van Halen take a noticeable break from their showy heavy metal-like distorted guitars and loud drums. Eddie Van Halen recorded his guitar part on a Fender Stratocaster plugged direct into the studio mixing console. The song is one of only two Van Halen tracks featuring Sammy Hagar playing a rhythm guitar part, which he played on a Gibson acoustic. The music video for the song features the band playing against a plain white background with quick cuts to women dancing. The version of the song on their 2004 compilation The Best of Both Worlds stops mid-way through the outro, unlike the fade out on the OU812 version. On the Live: Right Here, Right Now concert footage Hagar introduces the song as being about sex, about being about females who don't carry on intercourse until their male partner's climax.
Early in 1989, the song peaked at #13 on the Billboard Hot 100 and #2 on the Billboard Main Rock charts.
