yes...the concept of music nowadays is gone..
they always use the same pattern for all the songs, but still, people like it. Even if it's simple it's still music.
I think we lost creativity, if you think about it, the older music(90's and so on) are more elaborated than the ones today. Now a song is composed of 4 chords. In the 90's the use of b5, augmented, diminished chords was commonly used, now I can't see any diminished chord in any song.
And this are the bands that most people like, for example, green day. Their album american idiot can be played by almost anyone who know basic guitar(my case)
and yet, they win money for just using power chords..
I have nothing against them, it's just that we lost the creativity..
(personally I like some songs of green day)
Then, the bands that do good music aren't well known..
