Happy National Pig Day! We're celebrating all of the little oinkers of the world by listening to some of the most strange and unique songs dedicated in their honor. Who knew these guys had so many songs written about them?

1. "Pigs" by Pink Floyd

This song comes from the 1977 album Animals. The album is in three parts, “Dogs,” “Pigs,” and “Sheep.” The pigs represent the people who Roger Waters consider to be wealthy and powerful, at the top of the social ladder. During his guitar solo, David Gilmour used a talk box to mimic the sound of pigs. This was the first time Pink Floyd used a talk box in one of their songs, but definitely not the last.

2. "Piggies" by the Beatles

Released on The White Album in 1968, "Piggies," written mostly by George Harrison, features lyrical contributions from both John Lennon and Harrison's mother Louise.

George Harrison said of the song, "Piggies is a social comment. I was stuck for one line in the middle until my mother came up with the lyric, 'What they need is a damn good whacking' which is a nice simple way of saying they need a good hiding. It needed to rhyme with 'backing,' 'lacking,' and had absolutely nothing to do with American policemen or Californian shagnasties!"

The Stanley Brothers were an American bluegrass duo made up of brothers Carter and Ralph Stanley. This song comes from the album On Radio, and has been famously covered by artists like Old and in the Way and Phish.

5. "Guyute" by Phish

Released in 1998, "Guyute" is a favorite among Phish fans. The song tells the story of a pig named Guyute who not only pulls weapons from his coat, but also speaks in strange languages and hypnotizes the narrator. In 2000, shortly after Phish took a break, guitarist Trey Anastasio turned this song into orchestral piece for the Vermont Youth Orchestra.

6. "Run Pig Run" by Queens of the Stone Age

Released on the album Era Vulgaris, "Run Pig Run" is full of blasts of screaming metal fury. This track includes a guest appearance by multi-instrumentalist Alan Johannes, and is the perfect song to chase a pig around to, if you were into that kind of thing.

7. "War Pigs" by Black Sabbath

The opening song on the album Paranoid, "War Pigs" was originally titled “Walpurgis.”

"Walpurgis is sort of like Christmas for Satanists. And to me, war was the big Satan", said bassist and lyricist Geezer Butler. "It wasn’t about politics or government or anything. It was [about] evil. So I was saying 'generals gathered in the masses / just like witches at black masses' to make an analogy. But when we brought it to the record company, they thought 'Walpurgis' sounded too Satanic. And that's when we turned it into 'War Pigs'. But we didn't change the lyrics, because they were already finished." https://www.youtube.com/watch?v=K3b6SGoN6dA

8. "Pigs in Space" by Mickey Hart

Released in 1990 on Hart’s first album At the Edge, the song was created with the intention to romanticize the drums and experimentation. Writer Bob Tarte described the song as, "[Feeling] like you're at the edge of the rain forest listening to this atmospheric recording that uses a variety of unusual instruments and employs such musicians as Jerry Garcia, Babatunde Olatunji, Airto Moreira, and Zakir Hussain."

9. "Pigs in Zen" by Janes Addiction

Released on their debut album Jane's Addiction, also known as Triple-X or XXX, was rerecorded in an attempt to capture the energy they were known for. This song was known as the band's "anything goes" track, which inspired other songs such as "Bobhause" and "Blood Rag."

The band explained the deeply-rooted song in an interview, "I read the Gita, I read Black Magic Crowley, the Bible, anything I could get my hands on. If you want to talk to me about reaching nirvana, reaching Zen, well, the pig is closer than we are because the pig doesn't have material possessions. He f*cks when he wants to, he eats when he's hungry, and he sleeps when he's tired. that's the whole point of Zen. That's exactly what pigs do...so, 'Pigs in Zen.'"

10. "March of the Piggies" by NIN

"March of the Piggies" was released in 1994 as the first single from The Downward Spiral, NIN's second album. This song has become a NIN staple, and is featured in the video game Rock Band for both Xbox 360 and Playstation 3, as well as in an episode of Beavis and Butt-Head. In an interview, Trent Reznor explained the meaning behind the song as, "[Being] anywhere from the media to the people he thought were friends around him."

11. "Pigs" by Cypress Hill

Although this has nothing to do with an actual pig, this is certainly an important song to add to the list. The track, produced by DJ Muggs, was also created into a lullaby by artist Rob Getzschman in 2012, which is a drastic twist from the original tune.
