if using the same chords as another song in the same progression is a crime, then most musicians would be locked up. I can't count the number of popular songs over the past 15 years that use the standard F C D Bb pattern. If your riffs and lyrics are different and all you're "copying" is the chord pattern, I see nothing wrong with that.


now if you are singing your new lyrics the same as the original, that would be a problem
