If you were jamming along in your car to Robin Thicke's smash hit, "Blurred Lines," and thought, "this sounds very familiar," you're not the only one. Marvin Gaye's family thought the same thing.
The Gaye family alleges that "Blurred Lines" borrows heavily from Gaye's "Gotta Give it Up." You can consider the similarities in this YouTube mashup.
Now, Thicke's lawyers have filed a preemptive suit against the Gaye family, denying he copied the song. Instead, the attorneys say "Blurred Lines" was written to evoke the sound of the 1970s, Gaye's musical era.
