Massive Multiplayer Crossover / Music

• In the hip hop world this is known as a "posse cut," which is a song that features at least four consecutive verses by a different rapper. For example, "The Anthem" by Sway & King Tech, featuring RZA, Tech N9ne, Eminem, Xzibit, Pharoahe Monch, Kool G Rap, Jayo Felony, Chino XL, and KRS-One.
• Pigface is the side project of over one hundred musicians. While their individual tracks typically don't have a massive number of musicians, the credits to their albums are quite staggering, as most of them feature well over a dozen performers.
• Weezer's "Pork and Beans" music video. It's got almost everything that ever appeared on YouTube short of OK Go and The Angry Video Game Nerd.
  • There's an updated version. It is as though the internet gave birth.
• Blake Shelton's 2013 single "Boys 'Round Here" features a huge cast of characters: co-writers Dallas Davidson, Craig Wiseman, and Rhett Akins (father of Thomas Rhett); producer Scott Hendricks; the Pistol Annies (Blake's then-wife, Miranda Lambert, along with Ashley Monroe and Angaleena Presley); and The Voice finalist RaeLynn (Blake is a judge on that show).
  • Exaggerated on a remix released in June 2013 which has Jason Aldean, Luke Bryan, Ronnie Dunn, Miranda Lambert, Reba McEntire, Brad Paisley, Josh Turner, Keith Urban, and Hank Williams Jr. performing the "red, red, red, red, red, red, red, red, redneck" in the opener (which was done by Davidson on the original).
• Hank Williams Jr. has done this several times:
  • His cover of his father's "Mind Your Own Business" had Reba McEntire, Tom Petty, Willie Nelson... and New York evangelist Reverend Ike.
  • His 1988 single "Young Country" featured several up-and-comers and also-rans: Butch Baker, Steve Earle, Highway 101, Dana McVicker, Marty Stuart, Keith Whitley, and T. Graham Brown, and that's not even covering the music video.
  • In 1999, Chad Brock did a Millennium Bug-themed remake of Hank Jr.'s "A Country Boy Can Survive" that featured Hank Jr., George Jones, and John Anderson (whose part was cut from the radio edit).
  • 2006's "That's How They Do It in Dixie" featured Big & Rich, Gretchen Wilson, and Van Zant.

Loudermilk, Willie Nelson, Norma Jean, Jerry Reed, Connie Smith, Hank Snow, Porter Wagoner, and Dottie West.
• Many Charity Motivation Songs are massive gatherings of famous singers. "Do They Know It's Christmas?" (which gets re-recorded basically every Christmas with new people) and "We Are the World" are the most famous example.
• The credits to Mike Watt's first solo album practically reads like some kind of Alternative Rock hall of fame thanks to collaborations with literally dozens of musicians with their own bands. To list everyone who collaborated on the album would create a massive wall of text, so just take a look at his touring band at the time: Watt, himself, on bass and vocals, Eddie Vedder on vocals and guitar, William Goldsmith on drums, Dave Grohl alternating between drums and guitar, and Pat Smear on lead guitar.
• In 1995, Reba McEntire covered Patti LaBelle and Michael McDonald's "On My Own" with guest vocals from Trisha Yearwood, Martina McBride, and Linda Davis (best known for having previously worked with Reba on the 1993 hit "Does He Love You", and for being the mother of Lady Antebellum's Hillary Scott).

The song was well-received enough to be released as the year's Children in Need single (and became the Christmas #1 in Ireland, staying atop their singles chart for 7 weeks).
  • According to That Other Wiki there were also two other versions of the song, one sung by all female singers and one by all male singers.
• In October 2014, the above-mentioned "Perfect Day" received a Spiritual Successor in the form of a cover of The Beach Boys' "God Only Knows" (also released as a Children in Need single while simultaneously marking the launch of BBC Music), featuring that band's lead singer Brian Wilson, along with the likes of Florence Welch, Lorde, Sam Smith, One Direction, Elton John, Paloma Faith, Kylie Minogue, Stevie Wonder, Brian May, Pharrell Williams, Dave Grohl, Chrissie Hynde, Jamie Cullum, Chris Martin, and Emeli Sande. It has to be seen to be believed.

Randy Travis also makes a cameo in the song's music video, although he does not sing on the song due to his stroke.

• Santana struck gold once he got a lot of famous guests in Supernatural: Dave Matthews, Everlast, Rob Thomas, Lauryn Hill, Cee-Lo Green, Wyclef Jean, Maná, Eagle-Eye Cherry, Eric Clapton... the critical and commercial success led him to repeat the formula in the next two albums, Shaman (Michelle Branch, Seal, Macy Gray, P.O.D., Dido, Placido Domingo, Chad Kroeger - replaced by Alex Band in the single) and All That I Am (Branch again, plus Steven Tyler, Big Boi, Mary J. Blige, Joss Stone, will.i.am, Sean Paul, Kirk Hammett...).
• Dave Grohl decided to follow a mellow Foo Fighters album by recording some nasty, heavy instrumentals and inviting some of his metal idols to add lyrics and vocals. The resulting album, Probot, has quite the line-up: Cronos, Max Cavalera, Lemmy, Kurt Brecht, Lee Dorian, Tom G. Warrior, Snake, King Diamond... plus some guitar by Kim Thayil and in a jokey hidden track, Jack Black!
• The 1992 film Falling from Grace featured in its soundtrack the song "Sweet Suzanne", performed by John Mellencamp (who also directed and starred in the movie), Dwight Yoakam, and alternative country songwriters John Prine, Joe Ely, and James McMurtry (son of the film's writer, Larry McMurtry), an ensemble credited as "Buzzin' Cousins".
