Each to their own, Stereo. I've listened to Arcade Fire after them being recommended to me by someone. Did nothing for me at all - and I tried. They have a major problem in that none of them can sing.
Joking aside, music is very subjective like any art. Some of the stuff posted on this thread posters have said it moves them and I find it's music that I've heard a million times before and doesn't do anything for me at all. Guitar bands in particular I find characterless and boring. They are all much of a muchness. When I was growing up in the 70's there were all sorts of things happening - something for everybody. Today I find the standard of musicianship as gone down the plug hole by and large but people still seem to get a kick out of it. Baffles me but it's probably an age thing.
Early Radiohead was brilliant until Thom went all experimental, fiddling with 'sounds' as opposed to 'songs'. It was then I stopped listening. As for Incognito, I doubt they play what they play because it's difficult. It's just good.
I do take issue with this though: ".
..wonderfully technical musicians rarely make great music, only music played extremely well." I don't buy that because although I agree that you don't have to be a great musician to write good songs (Chris Martin for example?), if you follow your logic it's only average musicians that are the most creative. That can't be true. Great musicians have made great music for centuries because they have the wider ability to express themselves and aren't limited by their own technical shortcomings. Mozart was an extremely technically gifted pianist, for example, and would never have been able to achieve what he did otherwise. Some of Rachmaninov's piano concertos can't be played by anyone who isn't a virtuoso level player - because he was. His stuff is seriously good by the way.
The key words in your statement are "
great music" though - and that's subjective isn't it?
I saw a video on You Tube recently with Donald ***en (Steely Dan) explaining how he came to write '
Peg' on the piano - the chord progressions etc. I love that song not because it's difficult or technical (and it is) but because it's a great song that
happens to be difficult and technical. Someone commented that they wondered if Taylor Swift wrote songs that way.

I seriously doubt it.
