A great artist can change society because of the entertaining and mesmerizing quality of his or her art.

To be entertaining and educational and enlightening, all at once, this is a good goal to have.

There are people who are great technical players like Eric Clapton, and there are people who are great intuitive songwriters like Daniel Johnston. There are sometimes people who are great at both the technique and the creativity, the two sides of the coin, maybe Jimi Hendrix.

It's all easier said than done, and it isn't even easy to say.

I do feel pretty lucky that I'm not so great at playing and singing, it forces me to make sure I've really got something worth presenting because I can't rely on any kind of virtuosity to dazzle people with.

I never felt like I had a surface image to rely on that people would like - I always felt like my music would not be very fancy music, my voice is not very fancy, there is nothing hiding me from the audience.

In the past, Koreans have mostly copied other countries' engines, and so there's been kind of a problem with quality and a real limit on what they could do with that.
