Already knee-deep in a lawsuit over unpaid royalties against Lil Wayne, Jim Jonsin may now have to face the other side of the law. The super-producer behind hits like “Lollipop” and T.I.’s “Whatever You Like” is now being sued by South Florida producer Jason Jaggon over the beat to Slim Thug’s 2009 hit single “I Run.”

According to Jaggon, Jonsin used his previously copyrighted beat called “Just C U” without ever approaching Jaggon about the usage, thus violating the copyright. Jaggon claims he had shared some of his beats with a friend in 2008 who said he had connections within the rap industry who would be interested in purchasing his copyrighted work. In February 2009, Jaggon realized that Slim Thug’s hit single “I Run” featuring Yelawolf bore an all-too-telling similarity to his original beat.

In addition to Jonsin, Jaggon is also suing Rebel Rock Entertainment, E-1 Entertainment and Koch Entertainment for reeasing and profiting off the song. A full transcript of the suit can be found here.
