Justin Timberlake Record Label Sued For 'Suit & Tie'

Justin Timberlake and Jay Z's hit song "Suit & Tie" was not exactly buttoned up, legally speaking .According to a group that's suing, claiming the track ripped them off.

Two members of Sly, Slick and Wicked a '70s R&B group  filed the lawsuit, and in the docs they say "Suit & Tie" samples their song, "Sho' Nuff" ... which was released in 1973. It's no lightweight hit  none other than James Brown produced it.

The band members say Justin's record label, Universal Music Group, paid to sample the song -- however, never got the rights to the vocal performances in that song. Their bottom line ... we did the singing, but we didn't get paid.

Making matters worse  they say UMG then licensed "Suit & Tie" for a Bud Light commercial -- and the SS&W guys didn't get paid for that either.

They point out Justin's song was HUGE -- 3 million copies sold, and 92 million YouTube views and they want their piece of the pie  from UMG, Anheuser-Busch, and other publishers and producers of the track.
