I've always mixed my music by myself. Of course, there will always be some complications here and there, but it's never a problem.
For me, creating music is a completely natural thing. I've been doing so, and I will continue doing so. I record almost everything I play at home.
If by noise you mean uncomfortable sound, then pop music is noise to me.
Life ain't a concept. Music is not a concept. My titles are poetic abstractions of something that is with me all the time, not necessarily in music, but in life. Everybody's life.
