"In Ha Mood" is one of Ice Spice's biggest hits.

She's been accused of stealing it.

D.Chamberz is suing Ice and her producer RIOT for swiping their hit from his track "In That Mood," which dropped a year earlier.

Chamberz cites similarities in the tracks' beat, lyrics, hook, rhythmic structure, metrical placement, and narrative context.

He theorizes RIOT, a New Yorker, and/or Ice heard "In That Mood" on Hot 97, which gave it play.

Chamberz wants half of "In Ha Mood"'s publishing as well as damages.

No word from Ice Spice's camp.
