Carly Rae Jepsen And Owl City’s Adam Young are being sued over allegations of copyright infringement in a new lawsuit filed in California federal court.

The lawsuit was filed by Alabama-based singer and songwriter, Allyson Nichole Burnett and involves her 2010 song, “Ah, It’s a Love Song.”

The complaint alleges that a prominent motif of Burnett’s song was used to create the pop hit “Good Time” which was released by Jepsen and Young in June this year and reached No. 8 on the Billboard Hot 100.

According to the complaint, the hook in Burnett’s song is a “unique vocal motif” that is repeated throughout the song and “has a catchy pop vibe that both draws people in and sticks in people’s heads.”

Allyson says in her complaint that “many consumers may incorrectly assume that Burnett copied her own Original Motif from the Infringing Songwriters due to the widespread popularity and publication of ‘Good Time.’ Burnett’s reputation as an independent artist will be significantly damaged by such incorrect assumptions.”

Often referred to as Ally “Cupcake” Burnett, Allyson is best known as the voice and co-writer behind the theme song for MTV’s show, The Seven, and has had several of her songs featured on the network’s hit show, Jersey Shore.

Carly Rae Jepsen is best known for her hit song, “Call Me Maybe”, whilst Owl City’s “Fireflies” gave Adam Young a No. 1 hit in late 2009.

According to Billboard, several publishing companies and performing rights groups are targeted by the lawsuit in addition to the singers, including Universal Music Group, Songs Music Publishing and Schoolboy Records, who are also named as defendants. ASCAP and SESAC, two entities that collect performance royalties, have also apparently been dragged into the dispute.
