Justin Bieber and Dan + Shay Sued for Copyright Infringement Over Hit Song '10,000 Hours'

Companies have filed suit against Justin Bieber and Dan + Shay over a copyright infringement.

On Thursday, International Manufacturing Concepts, Melomega music and Sound Gems sued the pop singer

and the country music duo among others over their song "10,000 Hours," according to PEOPLE

Justin and Dan + Shay stole the core portion of their collab from a song written way back in 1973 called, "First Time Baby Is a Holiday."

It was originally written by Palmer Rakes and Frank Fioravanti. The song was finally released in 2014.

In the docs, the companies who say they own 'First Time' claim it's unmistakable how similar the song is to "10,000 Hours"

alleging JB and D+S copied the chorus, verse and hook and tried to pass it off as their own.
