re: Why is there no "great" music anymore?

I think this subject has more to do with writing music than anything else, but it's all opinion no matter how you look at it.
The Beatles practicing for 10000 hours does not mean they played the greatest music. I'm not saying they didn't play good music, but thats not what made it. It was the sound they chose for that time. What if the Beatles with all of that practice, had decided they wanted to play jazz, or country, or anything else. Would they still be considered as great as they were?

Great talent does not equal the greatest music.

There are many bands today that are very talented. But they choose to play a style, or type of music that I just do not care to listen to one bit.

Christina Aguilera has an amazing voice, but I can not stand her type of music she sings. That is just my opinion that I am entitled to, but obviously, someone likes her music.
