1. The Shins on Gilmore Girls
Gilmore Girls is known for their fast paced dialogue and countless pop culture references, often mentioning numerous artists an episode, so it would make sense that Rory and co would stumble upon a hip new band playing in a club while on spring break. James Mercer and band play "So Says I" for an uninterrupted minute and a half, which is a pretty impressive amount of airtime for television. Rory and friends don't arrive until the last song, though, so we can assume they are the worst concert goers ever. Shortly after you can hear "The Laws Have Changed" by The New Pornographers while Rory and Paris uncomfortable try to fit in with the club-goers stating, "no one can sniff out the hip like we can."
2. The Decemberists on Parks and Recreation
The Decemberists get about 30 seconds of airtime playing "Crane Wife 3" at the Pawnee-Eagletown unity concert. While they might not have gotten as much airtime as deserved the entire episode was full of additional musical guest such as Jeff Tweedy, Ginuwine, and Yo La Tengo.
3. Jack White on Portlandia
Jack White magically appears on the Portlandia sketch "The Studio" in which Fred's character portrays a man who has a "top notch" studio with overwhelming similarities the studio used when recording the Beach Boy's album Pet Sounds. Jack White magically appears and silently watches Fred's character as he struggles to make sense of it all. The lack of dialogue from White makes his facial expressions even more hilarious and one of the best musical guest Portlandia has locked down.
5. Death Cab For Cutie on The OC
Death Cab was famously the favorite band of OC stud Seth Cohen, despite Summer's less-than-flattering analysis, "it's one guitar and a whole lot of complaining." When the band finally appears they play a show at the infamous fictional venue, The Bait Shop, and were featured on the official soundtrack.
6. Prince on New Girl
Prince, the majestic being himself, guest stars in an episode of New Girl. In the episode, he plays himself and gives Jess (portrayed by Zooey Deschanel) relationship advice. The highlight, though, is when the The Purple One asks, "Do you like pancakes?"
7. Beck on Futurama
After Bender is hospitalized he discovers Beck's disembodied head is occupying the bed next to him. Beck then loans Bender a set of neck-mounted robotic mini-arms, and the two go on tour together as Bender uses the arms to scrape across his mangled body and earn the position of Beck's washboard player. As the episode continues, Bender writes a song about broken robots, and the duo decide to put on a benefit concert in San Francisco to help all the disabled machines. While helping Bender write a song about his feelings, disembodied Beck explains how emotion is an important part of his musical process as well, saying, "When I'm upset I write a song about it. Like when I wrote 'Devil's Haircut,' I was feeling really... what's that song about?"
8. The Beach Boys on Full House
The Beach Boys have a long standing friendship with the Tanner family, appearing in not one, not two, but three separate episodes. The most notable episode is the one in which DJ wins two tickets to the Beach Boys show but has the tricky decision of picking which family member to take. Naturally, The Beach Boys show up and invite the whole bunch along (except for baby Michelle) to the show where they sing and do some sort of a line dance on stage.
9. Radiohead on South Park
In this particularly dark episode, Cartman vows to take revenge after being tricked by eighth grader Scott Tenorman. Upon learning that Radiohead is Scott's favorite band, Cartman writes a letter to Radiohead claiming that Scott is a victim of "cancer, in his ass" and the British rock band visits South Park just in time to watch Scott cry after hearing he ate his parents.
10. Sir Paul McCartney on 30 Rock
In one of these two brilliant episodes of 30 Rock, Sir Paul McCartney appears as himself to prove the point that "it's live TV, anything can happen." The look on Alec Baldwin's bewildered face as Paul McCartney grins and slaps Baldwin's face makes this one of the best moments of 30 Rock's entire seven season run.
