All musicians - except perhaps Gene Simmons - say "for me it's not about the money, it's about music". It's just a thing they tend to say. Of course they care about money, but I don't think it's exactly "lying" when they say they only do something for the music. Musicians's motives don't have to be more "pure" than everybody else's, so I don't understand why they always have to play down the monetary side of things in public.

Which, again, reminds me of my favorite Freudian slip. Don Felder: "For me it's all about the money...the music".
