The “Knocked Up” soundtrack song list is a coveted one, mainly because no real soundtrack for the film exists, at least, not in the traditional sense. The only collection available for the film is “Strange Weirdos: Music From & Inspired by the Film ‘Knocked Up’” and features a variety of music from Loudon Wainwright III, some of which is featured in the film and others that were inspired by it. The following list comprises some of the main songs that should have been on the “Knocked Up” soundtrack song list.

“Shimmy Shimmy Ya” by Ol’ Dirty Bastard. 

This smooth track from rapper Ol’ Dirty Bastard and one of the founding members of the Wu-Tang Clan, gets the “Knocked Up” soundtrack started out right and with good reason. It’s also the opening track in the film.  

“We Are Nowhere And It’s Now” by Bright Eyes (feat. Emmylou Harris).

This piece from indie rock singer Conor Oberst and country legend Emmylou Harris makes its way on this list because of the beautiful melodies and exquisite lyrics that have made Oberst famous.

“Rock Lobster” by The B-52's.

This nearly seven minute long novelty song by 70's rock band The B-52’s is perfect for “Knocked Up.” The song’s nonsense lyrics about beach parties, narwhals and bikini whales is enough to make the listener think they’re a little under the influence, something the main characters of the film know all too much about.

“Police On My Back” by The Clash.

This track by English punk band The Clash was humorously used while “Knocked Up’s” main character Alison frantically combs convenience stores for pregnancy tests after she believes she could be pregnant.

“Tropicana” by Ratatat.

This song from the electronic music duo is a must on this list, simply because it is used when we see ultrasounds of the main characters’ baby, indicating how old he/she is as time passes.

“Rock You Like a Hurricane” by Scorpions.

This classic hard-rock anthem has appeared in television commercials, television shows and countless films and their previews. Since it appeared in “Knocked Up,” why not include it on this list? It’s a great track.

“Ashamed” by Tommy Lee.

This track is appropriately played during the film when main character Ben, who has ceased his pot-smoking, lazy ways and reinvented himself, reunites with Alison as she goes into labor with their child.  

“Swing” by Savage.

The song that started it all. This song is played at the club where Alison and Ben meet and get close. . .an event which eventually leads to Alison’s unexpected pregnancy.

"Daughter" by Loudon Wainwright III.  This beautiful track from folk singer and actor Loudon Wainwright appropriately closes out the film with shots of Ben, Alison and their baby daughter, playing over the credits as photographs of the cast and crew and their children are shown.  

"Grey in L.A." by Loudon Wainwright III. Another track by Wainwright that was the basis for much of the instrumental work heard in the film. The version with vocals is heard during the film’s credits.
