It’s Always Sunny in Philadelphia

It's Always Sunny in Philadelphia is an American sitcom created by Rob McElhenney and developed with Glenn Howerton and Charlie Day, who also star alongside Kaitlin Olson and Danny DeVito. Rather than a music act, its Lyricser entry gathers the show's original songs and musical bits, written by and performed by the cast as their characters — the self-styled bar-owning gang of «Paddy's Pub». Numbers such as «Nightman», «Troll Toll» and «Charlie Wants An Abortion» began as in-episode set pieces before taking on a life of their own with fans.

The show built its reputation on a willingness to let its characters be irredeemably selfish, petty and cruel to one another, wringing dark comedy from a friend group that would betray each other in an instant if it were convenient. That same appetite for taboo-poking, deadpan absurdity carries into its songs, several of which — «The N-Word», «The Gang Gets Racist», «The Gang Goes Jihad» — lean directly into the series' comfort with uncomfortable, satirical subject matter.

Musically the material sits between lo-fi novelty pop-rock and mock-theatrical bar-band earnestness, closer to musical-theater pastiche than any real genre movement. Its influence is mostly cultural rather than sonic: it fed a persistent tradition of scripted-comedy original songs becoming quotable internet artifacts, with Charlie Day's «Nightman» composition in particular often cited as one of the show's signature creative moments.
