@Acidicfriend Also I pointed out jazz is a form of taking what has come before and applying your own artistic style to it. Without properly learning and applying what has come before some would argue what you're creating is gibberish. (see previous post for more emphasis)
In the most simplistic example the transition into baroque music was characterized by the bending of the standards set forth by church music. Using more 'radical' minor key changes and having music follow the words (word painting) as opposed to straight music where the lyrics were more easily understood rather than being felt/expressed/illustrated.
Bringing this back I'm not saying that letsplays/montages are at the peak of creative endeavors. Instead I'm saying that 'copying,' what other people doesn't make it exactly the same. The fact I created it already makes it different. It may not be ground breaking, but it is different.
Your musical creations may be original, but without considering what is a 'pleasant,' sound how could you hope to make music that you and others would enjoy. Where does your idea of 'pleasant' sounds come from? It comes from your experience and what you have heard before (look up avant garde jazz some argue it's just nonsense while others say it's beautiful artistic expression). I'll qualify and say that what you do is at a more creative caliber, but don't say I'm copying pewdiepie etc and not trying to be different. I can attempt to emulate their success, but I will never be them.
