According to reports this week singer Ed Sheeran is being sued for a whopping £13million over a copyright issue with his 2015 smash hit song Photograph.

The pop star is accused of making a "note-for-note copy" of a song called Amazing, which was released as a track on X Factor winner Matt Cardle’s 2011 album Freedom.

The claim is being brought by California songwriters Martin Harrington and Thomas Leonard, who penned the Cardle track a few years before Photograph was even written. And to show just how serious they are, they’ve hired Richard Busch, the same lawyer who won the infamous Marvin Gaye lawsuit over infringement of Blurred Lines last year.

According to the lawsuit, both songs have similar choruses and share 39 notes in common identical in pitch and duration. Basically they are implying that young Ed and his writers have all but stolen their song, re packaged it and had a worldwide smash with their creation. To be honest I'm not so sure I agree. Yes it's undeniable that both choruses in each song are identical but at this stage in the game is any song truly an original piece of work? Surely common sense and reason must come into play at some point?

It would take two seconds to google ‘songs that sounds the same’ to which you'd be presented with a whole list of hits from the past 50 years alone that sound completely identical. Some credit Fats Domino, Chuck Berry and Elvis Presley with creating the Rock n Roll sound, so does that mean that their estates can now start suing every band and artist that has ever released a Rock n roll record since then? And why stop at songs, what about books? Most love stories have the same formula, so should authors start taking legal action against each other trying to prove who indeed came up with the original concept?

Last year I was working with my friend Tommy Chambers as I had decided to do an unplugged version of my 2004 album as part of my one woman show at the Glasgow Comedy Festival. We were in the studio and working on an arrangement for my song The Meaning of Love when Tommy turned and said to me “do you know this is almost the exact chords and notes in Unchained Melody?”

I laughed as I thought he was joking but then he started to play the song and I sang along only to discover that he was absolutely right. The song, for the most part, was in fact The Righteous Brothers hit with fresh words and melody sprinkled on top and I had never even noticed.

After I won Pop Idol I was rushed into a studio and given two weeks to recorded 18 songs that had been written by a variety of writers including Diane Warren, Gary Barlow and Lucy Silvas to name a few. I therefore wasn't included in the songwriting process of any of the album tracks and I suspect it would have been the same scenario for 2010 X Factor winner Matt Cardle.

It's a shame that more people don't realise this as I've seen some of the unnecessary abuse Matt has taken from people on social media sites who don't understand that it isn't Matt who is taking legal action against Ed Sheeran but the actual writers of the song.

As I said the writers Martin Harrington and Thomas Leonard, who penned the Cardle track have hired Richard Busch, the same lawyer who won the infamous Marvin Gaye lawsuit which I think was a terrible decision for the music industry.

In my humble opinion those songs sound at best sort of similar with a familiar beat but not enough to be deemed guilty of copyright infringement - but hey what do I know.

I actually think because of that verdict many many artists over the next few years will see their songs being scrutinised by fans online which could result in multiple legal proceedings. Music is food for the soul and we simply wouldn't have so many genres of it today if artists hadn't been inspired by each other's style and sounds over the years. It will be extremely interesting to see how this case unfolds should it in fact go to court. One thing is for sure both artists will see sales of their songs rocket as a result of all this publicity and we all know how the old saying goes “there's no such thing as bad publicity.”
