Ouch! This have got to MEGA hurt. The hit super song 'Timber' by Pitbull and Ke$ha's is apparently facing a multi-million dollar lawsuit over "copyright infringement" reports entertainment site Digital Spy (http://m.digitalspy.com/music/news/a580293/pitbull-keha-song-timber-in-multi-million-dollar-harmonica-lawsuit.html) It is alleged that songwriters Lee Oskar, Keri Oskar and Greg Errico are seeking $3 million in damages after claiming the harmonica riff in 'Timber' is identical to the one in their 1978 song. Mega ouch! Digital Spy further reports that the three claim that Paul Harrington, the harmonica player on 'Timber', was instructed to "emulate" the section on their song 'San Francisco Bay' to give it "an identical texture and sound". To make matters worse, the three also allege that Pitbull's label Sony "might have obtained a license" to use their song from a license holder, but insist they didn't receive permission from the songwriters themselves.
