I have around 38 songs copy written at the moment. I'm sure many of them have chord structures close to others songs that I may have never even listened to before. Does this mean I ripped these songs off? Most songs have predictable chord structures. It's almost impossible to come up with something original at this point. All you can hope to do is put your own spin and feel into a melody that someone else most likely came up with long ago. Many people have been saying that "kill for a dream" sounds like Rock Star by Nickleback...Does anyone think that they intentional had that in thier head and stole it when it was written? I bet with very little research I can find where Rockstar was a "rip off" of another song....When Liam comes out with "Hey Dude" or "suzie in the sky with diamonds" i'll be worried!
