This case involves a record company that owned the copyrights to seven musical compositions by a popular rock group. The record company had never licensed these songs for use in the karaoke industry. A karaoke company encoded compact discs with the audio version of the songs and with a contemporaneous video display of the songs’ lyrics. Karaoke enthusiasts who owned CD players with video outputs could then have the lyrics of the songs displayed on a video screen in “real time” as the songs were playing so that they could sing the lyrics along with the recorded artist. The karaoke company did not acquire synchronization licenses from the record company, but got compulsory licenses for the songs. The karaoke company had previously sent the record company a CD containing the songs and a notice of its intention to obtain compulsory licenses for the songs. The record company later informed the karaoke company that the CD infringed its copyrights in the songs. An expert in the music and pop culture industry and audio forensics/audio engineering was sought to opine on the issue.
