This is awesome. I was gonna post but then HG said everything I wanted to. I just love talking about music. In my radio show the last two weeks I compared guitar based music and electronic music. It was super fun. I was so pigeon holed into one having to be better for most of the time I was making plays list. By the end though I just realized you can't really separate the two in very many notable ways. It really just comes back to that music is a creative element and there are different tools to do that creation.
Important is very much defined in my mind as net influence on the future of music. That could be through making music, speaking about music, or even performing music. Musically though you can't really define one thing is better then another. Like Dave said about Gangman style, you can't really say one thing is better then another. You can compare their influence and effect on people, but not their quality of music. The residents have some die hard fans that lose their shit over the residents and Brittany Spears has lots of die hard fans that like her music. You can't say that the residents are better because they redefine what is music and you can't say Brittany Spears is better because she makes pop hits that huge amounts of people are interested in. It is really just all relative to preference.
Yeah big boi puts on a great live show. Tones of energy and shows off lots of his raw talent. He does a good job hitting a lot of his material by hoping from song to song mid song. It sounds like to could be annoying, be he does it really well and it keeps you hyped the whole time.
