We realise that there are only 12 notes to go around but still... there's inspiration and then there's bare-faced (alleged) theft.
Another case of plagiarism has hit the headlines as Ed Townsend, who composed and co-wrote the lyrics to Marvin Gaye's 1973 hit Let's Get It On has filed an infringement lawsuit against Ed Sheeran, relating to his song Thinking Out Loud.
The lawsuit apparently states, “The defendants copied the ‘heart’ of ‘Let’s’ and repeated it continuously throughout Thinking. The melodic, harmonic, and rhythmic compositions of Thinking are substantially and/or strikingly similar to the drum composition of ‘Let’s.’”
While the chords of Ed Sheeran's track are undeniably exactly the same, we're not quite sure about the rest of it - or why it's taken two years for Townsend to file the claim - but take a listen to the two tracks below and see what you think.
Of course, it's not the first time in recent musical history that someone's been accused of stealing elements of a Marvin Gaye track; that Blurred Lines ruling is still fresh in our minds.
While we wait for the outcome of this latest spat, here's our round-up of some of the most famous tunes that sound all too familiar.
