Rule one as a producer: make sure you get your samples cleared.

Apparently, that sentiment fell on deaf ears for Birdman as TMZ is reporting that his YMCMB label is now involved in another lawsuit. According to the report, two songs are under the microscope. Lloyd's "You," featuring Lil Wayne, and Glasses Malone's "Certified," featuring Akon, didn’t properly clear the samples used, which originated from Spandeau Ballet, a British rock group popular the 1980s.

The sampled artists have brought forth a lawsuit against Cash Money in which they’re seeking $3.3 million in damages for failing to initially pay up. “Certified” wasn’t a very big song for the label, however “You” was. In 2007, it peaked at #9 on the Billboard Hot 100 chart. It also claimed a #1 spot on the Hot R&B/Hip-Hop Songs chart with a remix of it featuring Nas and Andre 3000 being released shortly afterward.

This is just the most recent legal woe for Birdman and YMCMB. Most notable is their on-going legal bout with Lil Wayne, who has yet to withdraw his $51 million lawsuit even though he and Birdman have been pictured together numerous times since its filing.
