Look at popular music for the last 400 years. How is that any different than simply copying the previous generations stuff and putting your own spin on it?

If you heard a CD in 1986 then in 2015 you wrote a song subconsciously inspired by that tune, should I look down on you?

I mean, I'm not a huge fan of electronic music because the vast majority of it sounds the same to me, but I don't argue that they are not "real musicians".

I do think that some genres of music will age better than others, but that's a totally different topic.
