Liese S.:
I think there must be something to be said for musical integrity. There is inherently a difference between a tune that is written in your bedroom and sung to the stars alone, and a piece that has passed muster in a corporate label's marketing department by means of several revisions.
The creative process is informed by the industry side of things, and I believe there is a purity in expression that necessarily must be affected by the process of commercialization.
When a band or an artist begins to write (and I'm referring specifically to post-beatles self-contained musicians here, the work for hire stuff is a whole nother thing) there is no one to censor or edit them, good or bad. And I do mean musically as well as lyrically. Once an act is established, there is a process that each piece goes through, manager, producer, publisher, promotion, that affects the end product that the consumer gets.
Music may be slutty, capricious, commercially grubby, and bastard-born by nature, but at some point there is a tune whistled on a porch somewhere that means nothing but its beauty.
