Here’s a weird one. Robin Thicke’s monster summer hit “Blurred Lines” owes some obvious debt to older songs. In particular, Marvin Gaye’s almighty “Got To Give It Up” stands as a predecessor — the weird little percussion accents, the falsetto, the general sense of horniness. And sure, you could probably draw a lineage between the guitar-squiggles on Funkadelic’s “Sexy Ways” and the ones on “Blurred Lines.” I’m not a lawyer — and our resident lawyer just wrote his goodbye post — but those similarities don’t seem legally actionable; they just seem like musical influences. But apparently, the people who own the rights to those songs have been making noises about suing Robin Thicke. And so now Thicke — as well as T.I. and Pharrell, the other two guys on the song — are suing those rights holders, just to keep another lawsuit from happening. Make sense? No?
